5 Hilarious Horror Movie Bloopers

The best horror movies are spine chilling films bursting with vicious killers and gory deaths. Some of the best examples of this are creepy slashers like "A Nightmare on Elm Street," "Scream," and "Halloween," which will continue to fuel nightmares for many generations to come. The on-screen worlds of these movies produce a perfect blend of overwhelming fear and morbid curiosity, but only after their final cut.

A film production is a multi-million dollar undertaking that requires massive preparation, but no amount of money and planning can compensate for the fact that people are flawed. Onscreen, Ghostface, Michael Myers, and Pinhead are menacing, larger than life ghouls, but off-screen they're only human, which leads to mistakes and mischief behind the scenes.

Here are some of the funniest horror movie bloopers and gags caught on camera.

Since the release of "Scream" in 1996, the ongoing franchise has become one of the most popular examples of meta horror films. Self-aware teenagers with an SAT-level vocabulary openly discussing horror movie tropes, while actively experiencing them, made the first film a hit that has spawned four sequels. Onscreen, "Scream" characters are clever, precocious, and self-referential, but behind the scenes, the actors are just as clumsy as the rest of us.

In the climax of "Scream," the two killers, Billy Loomis (Skeet Ulrich) and Stu Macher (Matthew Lillard), are covered in corn syrup to simulate blood. After receiving a taunting call from Sidney (Neve Campbell), Billy angrily throws the phone, and marches off to find her. The sticky substance covering Ulrich's hands affected his aim, and the phone hit Lillard in the back of the head. Instead of breaking character, Lillard reacted to the unexpected smack by shouting, "You f***ing hit me with the phone, d***!" The hilarious reaction made it in the final cut.

'Halloween Kills' also has plenty of hilarious behind-the-scenes moments, but unlike Lillard's ad-lib, they weren't clever enough to end up in the film — but that's why gag reels and the internet exist.

Anthony Michael Hall appears in the sequel as an adult Tommy Doyle, the kid Laurie Strode babysits in the first "Halloween" movie. In one of the film's bloopers, the actor drives up to a gas station and gets out of the car without putting it in park. Hall reacts quickly, hops back in the car, and brings the vehicle to a stop. Whew, close one! The clip cuts to another take, where Hall hops out of the vehicle, only to laugh hysterically when the car begins to roll backwards. "I did it again," the Brat Pack actor admits after hopping back in the driver's seat and bringing the car to a stop again.

Geez, where's Mr. Vernon when you need him?

Pinhead has been the go-to guy for BDSM and torture since the first "Hellraiser" in 1987, and he always elicits a strong reaction. His scarred face, black eyes, and cool, measured voice either terrifies or excites, depending on what you're into.

British actor Doug Bradley has portrayed the leather clad sadomasochist in eight of the 10 films in the franchise, but even experienced horror actors can get a nasty case of the giggles.

In a behind-the-scenes clip from "Hellraiser: Deader," Pinhead stands with his back to the camera, preparing to instill fear in his next victim with a dramatic turn and hostile stare, but things don't go as planned. Bradley spins around, but instead of supplying the camera with a menacing stare, he laughs, which draws giggles from the crew around him. Bradley laughs along with them and points to the camera, saying, "Cut!" 

"Warm Bodies" is the story of a self-aware zombie, R (Nicholas Hoult), and his struggles being dead. His main conflict is his instinct to feed on humans, and his desire to experience emotions by consuming brain tissue, which is an understandably odd situation.

In one behind-the-scenes clip, Hoult sneaks up behind a man standing on a counter, pulls his legs out from under him, and drags him onto the floor. From there, Hoult is supposed to begin eating the poor guy, but the actor decided to take the scene in a very different direction. With his victim on the floor beneath him, Hoult lassos an invisible rope in the air and shrieks, "Squeal like a pig boy!"

Quoting "Deliverance" isn't always a crowd pleaser, but the crew of "Warm Bodies" reacted to the reference with approving laughter.

Anthony Hopkins' most famous role is that of Hannibal Lecter, who has a special way with words and human flesh. But the veteran actor has talent that goes way beyond a singular character. While filming "The Silence of the Lambs," a blood-soaked Hopkins took a moment to show off his ability to embody other characters.

Hopkins' mouth is covered in blood in the outtake as he stares down at the camera and begins to speak. Hopkins offers a pitch-perfect imitation of Sylvester Stallone's Rocky Balboa in place of Hannibal Lecter's articulate and refined speech. The best part is that the camera operator goes with it, and continues to film until Hopkins loses it, and the crew erupts into laughter.

There is no explanation as to why Hopkins suddenly decided to break character and become a southpaw, but it was probably a welcomed break from the intensity of face-chomping Lecter.

Horror films offer audiences horrifying and grotesque characters that demand attention and fear, and often leave viewers with an exhilarating blend of thrills and terror. The terror of horror films can dissipate when the credits roll, but the best ones foster a sense of dread that sticks around for bedtime. So, next time you find yourself spooked by popular horror villains, just remember, they fail, flub lines, and goof around just like you ... when they aren't stalking, torturing, and devouring their victims.
