Even more so than real-life clowns, movie clowns always seem to be the most unsettling. Or just downright scary. Maybe it's because the real clowns at the circus remain confined to their circus worlds, far away from where you reside, and movie clowns are on the screen right in front of you in your living room. Either way, the following clowns and the movies they appear in are guaranteed to get you calling for your mommy every night and begging her to check under your bed before you go to sleep. 

The hospital clowns from "Pee Wee's Big Adventure". Pee Wee Herman is injured on one of his new biker friends' Harleys in his debut movie. In a subsequent dream, a team of paramedic clowns brings Pee Wee's lost bicycle to a hospital, and the surgeon–also a clown–fixes it up. A grapple then picks up the bike and brings it to hell, an fiery subterranean world ruled by Pee Wee's evil neighbor, Francis. These clowns may have been helpful at first, but they've been scaring the daylights out of little kids and adults since the movie hit the silver screen in 1985. 

Shakes from "Shakes the Clown". Bob Goldthwait plays a drunken clown character in this classic 1991 movie. You don't need to worry too much about Shakes unless you happen to be a mime. Shakes hates mimes and is known to beat them up on occasion in a drunken rage. If you do happen to be a mime, do not hang out at a bar called The Twisted Balloon because your mom won't be there to save you. 

Cheezo from "Clownhouse". An identity theft story from hell, "Clownhouse" is a must-see for evil movie clown fans everywhere. Three patients escape from a mental hospital, kill three circus clowns–Cheezo, Bippo and Dippo–and steal their identities in this 1989 clown movie directed by Victor Salva. Michael Jerome West plays Cheezo's imposter, who leads the clown gang on a mission to terrorize three brothers in their home. Aside from his leadership role, Cheezo happens to be the most handsome of the trio with his poofed red-orange do and snazzy wardrobe. 

The clown from "Poltergeist". A clown doll can be quite scary, especially when your house is haunted. In the 1982 classic film directed by Tobe Hooper, a disturbed boy tries to get a good night sleep by covering his doll with a jacket. Granted, the clown stops staring at the poor boy, but it does wrestle him to the ground with its extendable elastic arms.

Pennywise the Dancing Clown from "It". Everyone remembers that crazy evil clown from the 1990 movie that's based on Stephen King's 1986 novel. One of the most memorable moments is when little Georgie's paper sailboat falls into a sewer drain where Pennywise, played by Tim Curry, just happens to be chillin'. He offers Georgie a balloon, and Georgie replies, "I'm not supposed to take stuff from strangers, my dad said so." Georgie's a smart kid, but not that smart. The dancing clown does manage to trick the boy into reaching for his sailboat before pulling him in. 

Captain Spaulding from "The Devil's Rejects". No list of scary movie clowns would be complete without this murderous clown from Rob Zombie's "The Devil's Rejects". In this 2005 flick, Captain Spaulding (Sid Haig) is the leader of a clan of serial killers who piss off the wrong sheriff by murdering his brother. The captain first began his career as a serial killer under the name Mr. Ding Dong a Bo-Bo before his son-in-law and accomplice, Otis B. Driftwood, renamed him Captain Spaulding. He also had other names during his tenure, such as Cutter.
