Revealing mistake: When Dana is walking down one hall with Leroy and a bottle of champagne, the exit sign is reversed. (00:53:05)
Revealing mistake: When Alex and Megan find the dead bodies in the dining hall, in the closeup shot of Dana, her neck pulsates. (01:09:05)
Revealing mistake: Toward the end of the movie, when Gallagher is trying to escape the elevator through the top, the wires for the Tunneler Puppet are visible in one shot. (01:16:10)
Revealing mistake: Dana enters her room and sees Neal sitting in the chair. Right at the part where she tells him that he can fool the others but not fool her, there's some smoke in the close up shot of Neal's face.
Revealing mistake: In the widescreen Blu-Ray, when Gallagher dies, his head twists to the side. When this happens, you can see that Blade's arm, which is hooked into his cheek, isn't attached to anything. His body isn't there. Likely, it was easier for them to just stick one of his arms into the actor's mouth than to attach the whole puppet. (The film was shot for video with the intention of being cropped down to fullscreen. The Blu-Ray presents the original, uncropped widescreen image, causing this mistake.)
