11 Facts About The Secret World of Alex Mack

The Secret World of Alex Mack was secretly one of the longer running series in Nickelodeon history, logging 78 episodes over four seasons from 1994 to 1998. It only ended because its star wanted out (we'll get to that). The show centered around the titular Alex Mack, who was doused with a mysterious chemical that gave her powers like morphing into goo, turning others into goo, and things that had nothing to do with goo, like shooting out electricity from her fingertips. Her only confidants were her bestie Ray and book smart older sister Annie, as the decidedly evil company that manufactured the chemical was out to find the student they knew was hiding their darkest secrets. Here are 11 things you may not have known, or may have completely forgotten, about the show.


Alex Mack co-creator and producer Thomas W. Lynch told the Los Angeles Times in 1994 that he wasn't interested in a girl who "looked like she worked too much in television, had the kinds of reactions you always see, the smile, the look, the acting with eyes and all that kind of thing." He saw 300 girls for the role. What set Oleynik apart? "Larisa had such a great natural instinct," he said. "It was stunning. She made the character richer and more shaded."


Nickelodeon's iconic Saturday Night block launched on August 15, 1992, starting with Clarissa Explains It All's second season premiere, "Crush." Clarissa and crew would remain at the 8PM EST slot for the next two years, all the way until the end of its original run. When it came time to replace the show, Nick decided to stick with a series with a female protagonist, and on October 8, 1994, Alex Mack replaced Clarissa, starting a night of programming that included Space Cases, All That, and Are You Afraid of the Dark? In another two years, Alex Mack would run new episodes twice a week on Tuesday and Thursday, replaced on the SNICK lineup by Kenan & Kel.


Alex Mack marked the television debut of actress Jessica Alba, who had made her film debut a little over a month earlier in Camp Nowhere. Alba would appear in the pilot and two other episodes of the first season as the snobby "Jessica," the girlfriend of Alex's crush Scott Greene. Jessica was designed to be hated: She wasn't just dating the likable main character's crush, but acted cruelly toward her, too. When Alba left to co-star on the television reboot of Flipper, Scott Greene got himself a new girlfriend, Kelly, who also antagonized Alex.

Only Alba's season of Alex Mack has currently been officially released on DVD; the cover has young Alba's face towards the upper left hand corner, touting the fact that it was her TV debut.


In the pilot, when Alex reformed back into a human after turning into goo, she would no longer be wearing clothes. The writers quickly gave the character the power to keep her clothing on in subsequent episodes, both because there was a minor controversy over it, and because they likely noticed the embarrassment of then 12-year old star Larisa Oleynik. When asked about the naked morphing years later, Oleynik said, "I remember being mortified! I was just really embarrassed, being that I was 12 or 13 or whatever. I had this towel wrapped around me or something and was behind some boxes. I was so, so embarrassed. They did then end up changing that ... which was a good thing."

Another issue was raised upon the United Kingdom's release of the season 1 DVD in 2012, when it was suggested by the BBFC (British Board of Film Classification) that anyone under 15 should not purchase a copy. The reason given was that in one scene a "child character" hides inside a tumble dryer, and the danger of doing such a thing is never addressed. The BBFC claimed that instead of cutting the scene, the distributor said they were fine with the rating because it was aimed for "an adult 'nostalgia' market" and not for children who wouldn't be familiar with the show anyway.


Lynch admitted in a 2012 story that it was costume designer Laura Slakey's idea to have Alex Mack wear hats. "She just threw this hat on and I was like, 'Wow, that's perfect,'" Lynch said. "The most iconic thing in the show, I had nothing to do with." Slakey was inspired by the way her father dressed in the 1960s; she imagined that Alex would dress differently since she didn't come across as a popular girl in the pilot script.

Initially, Nickelodeon didn't want the hats, but Lynch won that battle. Oleynik couldn't pick a favorite hat when asked years later, but she did bring up a lid she has never gotten out of her mind that the cast and crew referred to as the "condom cap."


Along with fellow creator Ken Lipman, Lynch wrote the pilot script for the show. Lynch's father was a nuclear physicist who worked with radioactive materials that he kept in the garage, providing some basic inspiration. Lynch's childhood is also how he came up with GC-161, the name of the chemical that gave Alex Mack powers. While GC was derived from "DNA research," 161 came about from divorce. Lynch was eight when his parents divorced, and 1 + 6 + 1 equals 8.


Louan Gideon played Danielle Atron, the evil owner/CEO of the Paradise Valley Chemical Plant. Gideon, however, might be best known as Becky Belding, Mr. Belding's one and only, from Saved by the Bell. She appeared in an episode giving birth to Zack Belding, named after Zack Morris, who was stuck in an elevator with Becky when she was in labor. She also appeared in an episode of Saved by the Bell: The New Class and on Seinfeld.


Between 1995 and 1998, 34 books featuring Alex Mack and company were published concurrently with the TV show. Only the first and last books, which were novelizations of the first and last episodes, didn't have original stories. The books ranged in length from 130 to 180 pages, and most were written by Diana G. Gallagher, a veteran author of books based on TV shows.


Larisa Oleynik was offered a fifth season, a feature Alex Mack film, and "a ton of money," according to Thomas Lynch, but Oleynik said she wanted to keep her character innocent, and that she was burnt out and wanted to finish high school. While that may be true, Larisa took on the role of Alissa Strudwick, Joseph Gordon-Levitt's girlfriend on 3rd Rock from the Sun, for 21 episodes soon after Alex Mack's end.


Matt Dearborn not only wrote seven episodes of The Secret World of Alex Mack, but directed three installments as well before creating the popular kids series Even Stevens. Vance DeGeneres—yes, Ellen's brother—wrote on the show before becoming an early Daily Show correspondent and writing for some Oscar telecasts. Writers Brian Hargrove and Jack Kenny would later co-create Titus. Neena Beber wrote the episode "False Alarms" before writing on Daria and penning the Mandy Moore movie How to Deal. Shawn Levy got his first TV show directing assignment on Alex Mack, eventually directing six episodes before helming Steve Martin's version of The Pink Panther, The Internship, Date Night, and all three of the Night at the Museum films.


In the final moments of the series finale, Annie checks up on Alex, who was just given an antidote by her scientist father that would rid her of all of her powers. Once Annie walks away, Alex pulls out the vial and smiles. Oleynik said that she played the scene not knowing if she takes the antidote or not: "You know, I never ... and I don't know what acting teachers would say about this, 'cause you're always supposed to have a choice ... but I never made that choice for myself when we were doing it. Just because I wasn't sure how I wanted the show to end in my mind." But Lynch revealed the answer in 2012. Spoiler alert: Alex Mack keeps her powers.

Big Questions
Why Does Turkey Make You Tired?

Why do people have such a hard time staying awake after Thanksgiving dinner? Most people blame tryptophan, but that's not really the main culprit. And what is tryptophan, anyway?

Tryptophan is an amino acid that the body uses in the processes of making vitamin B3 and serotonin, a neurotransmitter that helps regulate sleep. It can't be produced by our bodies, so we need to get it through our diet. From which foods, exactly? Turkey, of course, but also other meats, chocolate, bananas, mangoes, dairy products, eggs, chickpeas, peanuts, and a slew of other foods. Some of these foods, like cheddar cheese, have more tryptophan per gram than turkey. Tryptophan doesn't have much of an impact unless it's taken on an empty stomach and in an amount larger than what we're getting from our drumstick. So why does turkey get the rap as a one-way ticket to a nap?

The urge to snooze is more the fault of the average Thanksgiving meal and all the food and booze that go with it. Here are a few things that play into the nap factor:

Fats: That turkey skin is delicious, but fats take a lot of energy to digest, so the body redirects blood to the digestive system. Reduced blood flow in the rest of the body means reduced energy.

Alcohol: What Homer Simpson called the cause of—and solution to—all of life's problems is also a central nervous system depressant.

Overeating: Same deal as fats. It takes a lot of energy to digest a big feast (the average Thanksgiving meal contains 3000 calories and 229 grams of fat), so blood is sent to the digestive process system, leaving the brain a little tired.

More Details Emerge About 'Oumuamua, Earth's First-Recorded Interstellar Visitor

In October, scientists using the University of Hawaii's Pan-STARRS 1 telescope sighted something extraordinary: Earth's first confirmed interstellar visitor. Originally called A/2017 U1, the once-mysterious object has a new name—'Oumuamua, according to Scientific American—and researchers continue to learn more about its physical properties. Now, a team from the University of Hawaii's Institute of Astronomy has published a detailed report of what they know so far in Nature.

Fittingly, "'Oumuamua" is Hawaiian for "a messenger from afar arriving first." 'Oumuamua's astronomical designation is 1I/2017 U1. The "I" in 1I/2017 stands for "interstellar." Until now, objects similar to 'Oumuamua were always given "C" and "A" names, which stand for either comet or asteroid. New observations have researchers concluding that 'Oumuamua is unusual for more than its far-flung origins.

It's a cigar-shaped object 10 times longer than it is wide, stretching to a half-mile long. It's also reddish in color, and is similar in some ways to some asteroids in own solar system, the BBC reports. But it's much faster, zipping through our system, and has a totally different orbit from any of those objects.

After initial indecision about whether the object was a comet or an asteroid, the researchers now believe it's an asteroid. Long ago, it might have hurtled from an unknown star system into our own.

'Oumuamua may provide astronomers with new insights into how stars and planets form. The 750,000 asteroids we know of are leftovers from the formation of our solar system, trapped by the Sun's gravity. But what if, billions of years ago, other objects escaped? 'Oumuamua shows us that it's possible; perhaps there are bits and pieces from the early years of our solar system currently visiting other stars.

The researchers say it's surprising that 'Oumuamua is an asteroid instead of a comet, given that in the Oort Cloud—an icy bubble of debris thought to surround our solar system—comets are predicted to outnumber asteroids 200 to 1 and perhaps even as high as 10,000 to 1. If our own solar system is any indication, it's more likely that a comet would take off before an asteroid would.

So where did 'Oumuamua come from? That's still unknown. It's possible it could've been bumped into our realm by a close encounter with a planet—either a smaller, nearby one, or a larger, farther one. If that's the case, the planet remains to be discovered. They believe it's more likely that 'Oumuamua was ejected from a young stellar system, location unknown. And yet, they write, "the possibility that 'Oumuamua has been orbiting the galaxy for billions of years cannot be ruled out."

As for where it's headed, The Atlantic's Marina Koren notes, "It will pass the orbit of Jupiter next May, then Neptune in 2022, and Pluto in 2024. By 2025, it will coast beyond the outer edge of the Kuiper Belt, a field of icy and rocky objects."

Last week, University of Wisconsin–Madison astronomer Ralf Kotulla and scientists from UCLA and the National Optical Astronomy Observatory (NOAO) used the WIYN Telescope on Kitt Peak, Arizona, to take some of the first pictures of 'Oumuamua. You can check them out below.
