Moviefone's 8 Horror Movie Mistakes

After being attacked by a flock of crazed birds, Melanie lies down on a sofa to get bandaged up. When she sits up, you can see two large bloody scratches on her left cheek. But those scratches disappear when Mitch and Lydia walk Melanie outside to the car. Maybe she's a fast healer.

"Child's Play 2" was, arguably, equal parts creepy and funny, and this careless mistake definitely adds to the campy fun. When Grace (Grace Zabriskie) grabs Chucky in her office during a human-on-possessed-doll struggle, Chucky ultimately wins and stabs her twice, after which, Grace stumbles backwards. It's then that the top of a crew member's head finds its way into the shot. Someone's hair must've wanted its 15 minutes of fame.

Everyone in the Final Destination franchise dies in unique and unexpected ways. For example, in one scene, a boy is crushed by a piece of falling glass. The only problem is, the filmmakers didn't do a very good job of making sure the dummy they used for the scene looked realistic. You can see that its arms are way too long in proportion to the rest of its body.

Aside from the painfully obvious prop head, the scene in which Jason squeezes Rick's skull hard enough to make his eyes pop out reveals a little of what's behind the gory special effects. As you can see, a wire attached to the eyes of the faux head is clearly visible.

In the final scene, Jessica (Kari Keegan) runs over to Jason from behind and stabs him in the heart with a dagger. Jason then lashes back and hits Jessica, sending her flying backwards, and onto a clearly visible large blue crash mat. Safety first!

After Rick (Brendan Fraser) and Evelyn (Rachel Weisz) find the magical bracelet they've been looking for, water begins rushing in after them. They run to try to escape, but at one point stop to hold each other before a giant wave crashes over them. It's the moment before that happens when Weisz's and Fraser's stunt doubles are clearly visible. How'd they get in there?!

When Nancy wakes up from her nightmare in the dream clinic, we can clearly see a bandage on her chin. In the next shot, the bandage disappears, only to reappear in the next.

At the end of the movie, Sydney's (Neve Campbell) dad falls out of a closet he's been locked in -- but he wasn't alone. After Syd's dad pushes his way out, various items fall out with him, and you can clearly see a crew member's hand pushing/throwing items out of the closet behind him.
