15 Fateful Facts About Gilligan’s Island

Original image

The 98th—and final—episode of Gilligan’s Island was broadcast on April 17, 1967. Though never a critical favorite, the show was still a solid ratings hit and the cast and crew had every expectation of returning in the fall for a fourth season. But at the last minute CBS needed to find some room on the schedule for Gunsmoke, the favorite show of Babe Paley, wife of network president William Paley. So Gilligan got the axe and, at least as far as viewers know, the cast is still stranded somewhere in the Pacific.

Forty-eight years after that final wrap party, however, Gilligan’s Island is still on the air. It was sold into syndication and has been broadcasting reruns continuously in 30 different languages around the world. Just sit right back and you’ll hear some tales of everyone’s favorite castaways.


One day in a public speaking class at New York University, the professor had students compose an impromptu one-minute speech on this topic: If you were stranded on a desert island, what one item would you like to have? Sherwood Schwartz was a student in that class, and the question so intrigued him that it remained lodged in the back of his mind for many years.

After working for some time as a comedy writer for other shows, Schwartz decided to pitch his own idea for a sitcom. Thinking back to that desert island question, he thought it would make for an interesting dynamic to have a group of very dissimilar individuals stranded together and have to learn to live and work together. The island would be “a social microcosm and a metaphorical shaming of world politics in the sense that when necessary for survival, yes we can all get along,” Schwartz explained in Inside Gilligan's Island: From Creation to Syndication. Schwartz quickly discovered after his first few pitch meetings that words like “microcosm” and “metaphor” were not very helpful when trying to sell a comedy.


After getting a green light from CBS for the pilot, Schwartz went about assembling his cast. He chose the name of the bumbling first mate—Gilligan—from the Los Angeles telephone directory. Gilligan’s first name was never mentioned during the series, but according to Schwartz’s original notes, it was intended to be “Willy.” Yet Bob Denver always insisted that “Gilligan” was the character’s first name. “Almost every time I see Bob Denver we still argue,” Schwartz once admitted. “He thinks Gilligan is his first name, and I think it's his last name. Because in the original presentation, it's Willy Gilligan. But he doesn't believe it, and he doesn't want to discuss it. He insists the name is Gilligan.”


Jerry Van Dyke was Schwartz’s first choice to play the lead, but Van Dyke said that the pilot script was “the worst thing I’d ever read.” On the advice of his agent, Van Dyke accepted the lead in the short-lived (and critically panned) My Mother The Car instead. “I had a lot of problems with the agency, because they were trying to push me into taking [Gilligan’s Island],” Van Dyke recalled in an interview. “But that’s the joke: I turned it down and took My Mother the Car. But, again, it was really good, because I’d [have] been forever known as Gilligan. So that worked out, too!”


The Skipper was the toughest, and last, character to be cast. Schwartz auditioned dozens of actors (including Carroll O’Connor), but no one was quite right; he wanted someone strong and commanding, sometimes blustery and short-tempered, but able to show a genuine affection for Gilligan even when smacking him over the head with his hat. Alan Hale was filming Bullet for a Bad Man in St. George, Utah when he got the casting call for Gilligan and was unable to get time off for a screen test. So he had to sneak off set after a day of filming, which was no easy task. In Surviving Gilligan's Island: The Incredibly True Story of the Longest Three-Hour Tour in History, it was revealed that Hale made his way to Los Angeles to read a scene with Bob Denver via horseback, hitchhiking, airplane, and taxi cab. He reversed the process after the audition and made it back to Utah just in time to resume filming his western the next day.


The pilot for the series was filmed over several days in November of 1963 on the island of Kauai in Hawaii. The last day of shooting was scheduled for November 23, 1963 in Honolulu Harbor for the scenes showing the S.S. Minnow embarking on its fateful three-hour tour. Late in the morning on November 22, a crew member ran to the set and announced that he’d just heard on the radio that President John F. Kennedy had been shot. As Lyndon Johnson was sworn in as President, it was announced that all military installations (including Honolulu Harbor) would be closed for the next two days as a period of mourning. Filming was delayed by several days as a result, and in the opening credits—as the Minnow cruises the harbor—the American flag can be seen flying at half-mast in the background.


Natalie Schafer, who played Mrs. Lovey Howell—and allegedly only accepted the invitation to play Mrs. Howell because it meant a free trip to Hawaii to film the pilot—was a real-life millionaire. During her marriage to actor Louis Calhern, the couple had invested heavily in Beverly Hills real estate at a time when a house on Rodeo Drive could be purchased for $50,000.

When she died in 1991, Schafer bequeathed a large chunk of her fortune to her favorite teacup poodle (she had no children), with instructions for that money to be donated to the Motion Picture and Television Hospital after the pooch’s passing. Said hospital now has a "Natalie Schafer Wing." Rumor has it that Schafer also left a tidy sum to Gilligan’s Island co-star Dawn Wells (Mary Ann), who lived with and helped care for Natalie as she battled breast cancer.


All of the actors signed contracts that guaranteed them a certain amount of money per original episode plus a residual payment for the first five repeats of each episode. This was a pretty standard contract in 1965, when as a rule most TV shows were only rerun during the summer months as a placeholder between seasons.

Even though the word “syndication” wasn’t yet a standard term in the TV production glossary, Dawn Wells’ then-husband, talent agent Larry Rosen, advised her to ask for an amendment to that residual clause in her contract, and the producers granted it, never thinking the series would be on the air nearly 50 years later. As a result, the estate of the late Sherwood Schwartz (who reportedly pocketed around $90 million during his lifetime from his little microcosm-on-an-island show) and Dawn Wells are the only two folks connected to the show who still receive money from it.


The programming executives at CBS were underwhelmed by the pilot, but it managed to impress three different test audiences enough that they put the series on the fall schedule. But before filming for the first episode began, they had a few caveats—the first of which was replacing three cast members who had tested the “lowest” with audiences: John Gabriel, who played The Professor, a high school science teacher; Kit Smythe, who played Ginger as a secretary, not a movie star; and Nancy McCarthy, who played Bunny, yet another secretary. It was decided to make Ginger an actress, and Bunny was replaced by wholesome farm girl Mary Ann. One actress who auditioned for Mary Ann’s part was a young Raquel Welch, though something about her just didn’t scream “girl next door.”


Years after the show stopped filming (it’s never really been “off the air”), the cast members found fans in the most unusual places. For example, in 2001 Russell Johnson was asked to speak at a biochemical conference in San Francisco. “There were four or five hundred PhDs there, and every one of them was a Gilligan’s Island fan,” he recalled. Bob Denver took his wife to dinner at Chicago’s elegant Pump Room once and the trio of musicians immediately switched from playing their semi-classical chamber music to “The Ballad of Gilligan’s Island.” Dawn Wells was vacationing in the Solomon Islands in 1990 when she and some friends canoed to a remote island in the area that had no running water or electricity. The visitors were ushered to a hut to meet the village chief, and Wells was stunned when “The chief's wife said, ‘I know you. In 1979, I was going to nursing school in Honiara, the capital of the Solomon Islands, and I used to come home and watch you in black-and-white!’”


Alan Hale was an old-school “the show must go on” kind of actor. In Inside Gilligan’s Island, Schwartz recalled chatting with Hale at the season one wrap party when the actor, as jolly and convivial as always, happened to comment that now that shooting was completed, he could take care of his arm. When Schwartz asked what was wrong with his arm, Hale nonchalantly replied: “Oh, I broke it a few weeks ago.” He went on to explain that three weeks prior he had missed the crash pads slightly when he fell out of a coconut tree for a scene and had smashed his right arm on the stage. He hadn’t sought medical treatment because he didn’t want to disrupt the filming schedule. Schwartz was dumbfounded; “How did you manage to haul coconuts and lift Bob Denver with a broken arm?” “It wasn’t easy,” Hale admitted.


Even though Natalie Schafer was in her mid-60s when Gilligan’s Island was filmed, she insisted on doing the majority of her own stunts—and never complained about jumping into the lagoon or sinking in fake quicksand. In 1965, she told “Let’s Be Beautiful” columnist Arlene Dahl that she kept in shape by swimming in her backyard pool—in the nude—and by periodically following her special “ice cream diet,” which consisted of eating nothing but one quart of ice cream (spread out over three meals) daily. She would lose three pounds in five days following that regime.


Jim Backus, who played Mr. Howell, was beloved by his castmates. In addition to being the source of endless ribald jokes and a willing coach to the less experienced actors on how to ad-lib or deliver a punch line, he was also notoriously cheap. In What Would Mary Ann Do? A Guide to Life, Dawn Wells recalled how during the show’s first season he would often invite her and Natalie Schafer out to lunch … only to realize that he had left his wallet back at the studio when the check came. Before the cast departed for summer hiatus after the wrap party, Schafer presented Backus with a bill for a little over $300—the total he owed for all those meals.


In the first season of Gilligan’s Island, the opening credits ended with a picture of Ginger as the singers crooned “the moo-vie star” followed by a hastily added “and the rest.” The text accompanying the photo proclaimed: “and also starring Tina Louise as ‘Ginger.’” (The only other cast member whose character name was listed in the credits was Jim Backus, a show business veteran and very recognizable character actor whose resume was longer than Ginger’s evening gown.) Louise had had it written into her contract that, along with the “also starring” billing, no one would follow her name in the credits.

Once the show was renewed for a second season, champion-for-the-underdog Bob Denver approached the producers and asked that Russell Johnson and Dawn Wells be added to the opening credits, stating that their characters were just as vital to the dynamic as any of the others. When the producers mentioned the clause in Louise’s contract, Denver countered by referring to a clause in his own contract which stated that he could have his name placed anywhere in the credits he liked. He threatened to have his name moved to last place, so an agreement was hammered out with Louise, a revised theme song was recorded, and Johnson and Wells took their rightful place in the opening montage.


The lagoon set was specially built for the show by CBS on their Studio City lot in 1964. They’d originally tried filming two episodes in Malibu, but they had a lot of downtime due to fog. Of course, filming at the studio had its own set of problems; sometimes filming had to be halted when traffic noise could be heard from the nearby Ventura Freeway. And the water temperature would hover around 40 degrees during the winter months, forcing Bob Denver to wear a wetsuit under his Gilligan costume. In 1995, the lagoon was turned into an employee parking lot.


In the January 23, 1965 edition of TV Guide, an article about Bob Denver mentioned the on-set tension between Tina Louise and the rest of the castaways: “Denver will not say why he and the glamorous Tina [Louise] do not get along, nor will any of the castaways–they just ignore her, and she ignores them. Between scenes, while the other six principals chat and tell jokes together, she sits off by herself. And recently when Denver was asked to pose for pictures with her, he adamantly refused. Part of Louise’s dissatisfaction with the series was that she had expected to be the star of the show. (Her agent had allegedly pitched it to her as the story of an actress stranded on an island with six other people.)

Bob Denver eventually capitulated to network pressure and agreed to do a photo shoot with Louise for a TV Guide cover in May of 1965—but only if Dawn Wells was included. To his chagrin, Wells was cropped out of the final image.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning
May 21, 2017

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!

8 Common Dog Behaviors, Decoded
May 25, 2017
Original image

Dogs are a lot more complicated than we give them credit for. As a result, sometimes things get lost in translation. We’ve yet to invent a dog-to-English translator, but there are certain behaviors you can learn to read in order to better understand what your dog is trying to tell you. The more tuned-in you are to your dog’s emotions, the better you’ll be able to respond—whether that means giving her some space or welcoming a wet, slobbery kiss. 

1. What you’ll see: Your dog is standing with his legs and body relaxed and tail low. His ears are up, but not pointed forward. His mouth is slightly open, he’s panting lightly, and his tongue is loose. His eyes? Soft or maybe slightly squinty from getting his smile on.

What it means: “Hey there, friend!” Your pup is in a calm, relaxed state. He’s open to mingling, which means you can feel comfortable letting friends say hi.

2. What you’ll see: Your dog is standing with her body leaning forward. Her ears are erect and angled forward—or have at least perked up if they’re floppy—and her mouth is closed. Her tail might be sticking out horizontally or sticking straight up and wagging slightly.

What it means: “Hark! Who goes there?!” Something caught your pup’s attention and now she’s on high alert, trying to discern whether or not the person, animal, or situation is a threat. She’ll likely stay on guard until she feels safe or becomes distracted.

3. What you’ll see: Your dog is standing, leaning slightly forward. His body and legs are tense, and his hackles—those hairs along his back and neck—are raised. His tail is stiff and twitching, not swooping playfully. His mouth is open, teeth are exposed, and he may be snarling, snapping, or barking excessively.

What it means: “Don’t mess with me!” This dog is asserting his social dominance and letting others know that he might attack if they don’t defer accordingly. A dog in this stance could be either offensively aggressive or defensively aggressive. If you encounter a dog in this state, play it safe and back away slowly without making eye contact.

4. What you’ll see: As another dog approaches, your dog lies down on his back with his tail tucked in between his legs. His paws are tucked in too, his ears are flat, and he isn’t making direct eye contact with the other dog standing over him.

What it means: “I come in peace!” Your pooch is displaying signs of submission to a more dominant dog, conveying total surrender to avoid physical confrontation. Other, less obvious, signs of submission include ears that are flattened back against the head, an avoidance of eye contact, a tongue flick, and bared teeth. Yup—a dog might bare his teeth while still being submissive, but they’ll likely be clenched together, the lips opened horizontally rather than curled up to show the front canines. A submissive dog will also slink backward or inward rather than forward, which would indicate more aggressive behavior.

5. What you’ll see: Your dog is crouching with her back hunched, tail tucked, and the corner of her mouth pulled back with lips slightly curled. Her shoulders, or hackles, are raised and her ears are flattened. She’s avoiding eye contact.

What it means: “I’m scared, but will fight you if I have to.” This dog’s fight or flight instincts have been activated. It’s best to keep your distance from a dog in this emotional state because she could attack if she feels cornered.

6. What you’ll see: You’re staring at your dog, holding eye contact. Your dog looks away from you, tentatively looks back, then looks away again. After some time, he licks his chops and yawns.

What it means: “I don’t know what’s going on and it’s weirding me out.” Your dog doesn’t know what to make of the situation, but rather than nipping or barking, he’ll stick to behaviors he knows are OK, like yawning, licking his chops, or shaking as if he’s wet. You’ll want to intervene by removing whatever it is causing him discomfort—such as an overly grabby child—and giving him some space to relax.

7. What you’ll see: Your dog has her front paws bent and lowered onto the ground with her rear in the air. Her body is relaxed, loose, and wiggly, and her tail is up and wagging from side to side. She might also let out a high-pitched or impatient bark.

What it means: “What’s the hold up? Let’s play!” This classic stance, known to dog trainers and behaviorists as “the play bow,” is a sign she’s ready to let the good times roll. Get ready for a round of fetch or tug of war, or for a good long outing at the dog park.

8. What you’ll see: You’ve just gotten home from work and your dog rushes over. He can’t stop wiggling his backside, and he may even lower himself into a giant stretch, like he’s doing yoga.

What it means: “OhmygoshImsohappytoseeyou I love you so much you’re my best friend foreverandeverandever!!!!” This one’s easy: Your pup is overjoyed his BFF is back. That big stretch is something dogs don’t pull out for just anyone; they save that for the people they truly love. Show him you feel the same way with a good belly rub and a handful of his favorite treats.

The best way to say “I love you” in dog? A monthly subscription to BarkBox. Your favorite pup will get a package filled with treats, toys, and other good stuff (and in return, you’ll probably get lots of sloppy kisses). Visit BarkBox to learn more.
