11 Strange Movie Job Titles—Explained!

Here's what the key grip, best boy, and gaffer actually do, plus the origins of those titles.

1. Foley artist

A person who creates sound effects in post-production.

Film sets don’t necessarily have the same acoustic properties as the real-life locations they portray. Foley artists eliminate extraneous noises and add convincing sounds. For example, they stamp their feet to match footsteps on the screen. Also, (spoiler alert!) movie fistfights are faked. The blows never land, but Foley artists, shall we say, “punch up” the sound.

The job takes its name from Jack Donovan Foley, who rounded up employees with experience in radio sound effects to help Universal Studios survive the transition to sound in 1927.

2. Gaffer

The head of the electrical department for a film production.

Although some sources point to the fact that gaffer (probably an elision of grandfather or godfather) has long been used in British English for an old man, or the foreman of a work crew, Media-Match gives a more likely explanation: "The term was also used to describe men who adjusted lighting in English theater and men who tended street lamps, after the 'gaff' they used, a pole with a hook on its end."

3. Grip

A member of a camera crew responsible for building and maintaining all the equipment that supports cameras, as well as moving and setting up the equipment.

The term was adapted from the American theater where it was used for a stagehand who helps shift scenery.

4. Dolly grip

A grip who moves camera cranes and dollies (the wheeled platforms that carry the camera and the camera operator).

5. Key grip

The supervisor of the team of grips.

6. Best boy (grip/gaffer)

Second in command, assisting the gaffer or key grip.

According to IMDb, "The origin of the term is from 'pre-union' filming days when the line between Grip and Electric departments was less rigid. When the head of either department needed another body temporarily, he'd go to the head of the other department and ask him to 'lend me your BEST boy.' By default the 2nd in charge of either department came to be known as best-boy. This term may also have been borrowed from early sailing and whaling crews, as sailors were often employed to set up and work rigging in theatres. There are no 'best girls' per se; female chief assistants are also called 'Best Boys.'"

7. Child wrangler

“Animal wranglers”—like wranglers who manage horses and other livestock on a ranch—control, instruct and care for animals used in filming. Similarly, “child wranglers” manage child actors on a set, coaching them in acting and keeping them entertained and quiet when they are not in the scene being filmed.

8. Python wrangler

A jocular term for the utility sound technician who performs a variety of tasks in the Sound Department, most typically pulling cables.

9. Fixer

Someone who provides logistical support, facilitating whatever's needed relating to permits, customs, location, talent, crews, equipment, accommodation, and transportation for filmmakers who wish to conduct filming abroad. The term is apparently a wink at the colloquial term fixer, meaning a person who makes arrangements for other people, especially of an illicit or devious kind.

10. Craft service

The people who assist the crafts (camera, sound, electricians, grips, props, art director, etc.) during shooting, with tasks including providing snacks and cleaning the set. (“Catering” provides the main meals.)

11. Concept artist

A person who creates a computer-generated 3D model that allows the production designer to determine how a scene will ultimately look. The concept artist renders the desired shots, camera angles, focal lengths, camera movements and choreography. The computer-generated model can also depict surface textures, lighting schemes and costumes.

15 Confusing Plant and Animal Misnomers

People have always given names to the plants and animals around us. But as our study of the natural world has developed, we've realized that many of these names are wildly inaccurate. In fact, they often have less to say about nature than about the people who did the naming. Here’s a batch of these befuddling names.

1. COMMON NIGHTHAWK

There are two problems with this bird’s name. First, the common nighthawk doesn’t fly at night—it’s active at dawn and dusk. Second, it’s not a hawk. Native to North and South America, it belongs to a group of birds with an even stranger name: Goatsuckers. People used to think that these birds flew into barns at night and drank from the teats of goats. (In fact, they eat insects.)

2. IRISH MOSS

It’s not a moss—it’s a red alga that lives along the rocky shores of the northern Atlantic Ocean. Irish moss and other red algae give us carrageenan, a cheap food thickener that you may have eaten in gummy candies, soy milk, ice cream, veggie hot dogs, and more.

3. FISHER-CAT

Native to North America, the fisher-cat isn’t a cat at all: It’s a cousin of the weasel. It also doesn’t fish. Nobody’s sure where the fisher cat’s name came from. One possibility is that early naturalists confused it with the sea mink, a similar-looking creature that was an expert fisher. But the fisher-cat prefers to eat land animals. In fact, it’s one of the few creatures that can tackle a porcupine.

4. AMERICAN BLUE-EYED GRASS

American blue-eyed grass doesn’t have eyes (which is good, because that would be super creepy). Its blue “eyes” are flowers that peek up at you from a meadow. It’s also not a grass—it’s a member of the iris family.

5. MUDPUPPY

The mudpuppy isn’t a cute, fluffy puppy that scampered into some mud. It’s a big, mucus-covered salamander that spends all of its life underwater. (It’s still adorable, though.) The mudpuppy isn’t the only aquatic salamander with a weird name—there are many more, including the greater siren, the Alabama waterdog, and the world’s most metal amphibian, the hellbender.

6. WINGED DRAGONFISH

This weird creature has other fantastic and inaccurate names: brick seamoth, long-tailed dragonfish, and more. It’s really just a cool-looking fish. Found in the waters off of Asia, it has wing-like fins, and spends its time on the muddy seafloor.

7. NAVAL SHIPWORM

The naval shipworm is not a worm. It’s something much, much weirder: a kind of clam with a long, wormlike body that doesn’t fit in its tiny shell. It uses this modified shell to dig into wood, which it eats. The naval shipworm, and other shipworms, burrow through all sorts of submerged wood—including wooden ships.

8. WHIP SPIDERS

These leggy creatures are not spiders; they’re in a separate scientific family. They also don’t whip anything. Whip spiders have two long legs that look whip-like, but that are used as sense organs—sort of like an insect’s antennae. Despite their intimidating appearance, whip spiders are harmless to humans.

9. VELVET ANTS

There are thousands of species of velvet ants … and all are wasps, not ants. These insects have a fuzzy, velvety look. Don’t pat them, though—velvet ants aren’t aggressive, but the females pack a powerful sting.

10. SLOW WORM

The slow worm is not a worm. It’s a legless reptile that lives in parts of Europe and Asia. Though it looks like a snake, it became legless through a totally separate evolutionary path from the one snakes took. It has many traits in common with lizards, such as eyelids and external ear holes.

11. TRAVELER'S PALM

This beautiful tree from Madagascar has been planted in tropical gardens all around the world. It’s not actually a palm, but belongs to a family that includes the bird of paradise flower. In its native home, the traveler’s palm reproduces with the help of lemurs that guzzle its nectar and spread pollen from tree to tree.

12. VAMPIRE SQUID

This deep-sea critter isn’t a squid. It’s the only surviving member of a scientific order that has characteristics of both octopuses and squids. And don’t let the word “vampire” scare you; it only eats bits of falling marine debris (dead stuff, poop, and so on), and it’s only about 11 inches long.

13. MALE FERN & LADY FERN

Early botanists thought that these two ferns belonged to the same species. They figured that the male fern was the male of the species because of its coarse appearance. The lady fern, on the other hand, has lacy fronds and seemed more ladylike. Gender stereotypes aside, male and lady Ferns belong to entirely separate species, and almost all ferns can make both male and female reproductive cells. If ferns start looking manly or womanly to you, maybe you should take a break from botany.

14. TENNESSEE WARBLER

You will never find a single Tennessee warbler nest in Tennessee. This bird breeds mostly in Canada, and spends the winter in Mexico and more southern places. But early ornithologist Alexander Wilson shot one in 1811 in Tennessee during its migration, and the name stuck.

15. CANADA THISTLE

Though it’s found across much of Canada, this spiky plant comes from Europe and Asia. Early European settlers brought Canada thistle seeds to the New World, possibly as accidental hitchhikers in grain shipments. A tough weed, the plant soon spread across the continent, taking root in fields and pushing aside crops. So why does it have this inaccurate name? Americans may have been looking for someone to blame for this plant—so they blamed Canada.
