Continuity mistake: At the end of the film, when Dwight gets pulled into the room and sits down in a chair beside Ray and Buddy, Ray's shirt is orange. Then when Dwight says, "I can't feel my legs," it cuts back, but Ray's shirt is yellow. It alternates throughout this scene between orange and yellow. (01:06:00)

Continuity mistake: When Dwight is handing everybody goggles, cup walkie talkies etc., the red numbers on the machine nearby keep changing in most shots. You can clearly see "02.38.58" and it is counting down. Then in the next shot it is "02.39.48" and is counting up. Then it is "02.17.00" etc. (00:46:15 - 00:47:55)

Continuity mistake: In the opening scene when the priest is playing the piano, in close shots of him you can see the back of the musical sheets sitting on the piano, and they are just pages of musical notes.

Continuity mistake: When Cindy and Buddy are in the cool room and she is talking on the cups, you can see what appears to be blood on the bottom of her pants. In a scene cut from the film (it's on the DVD), Cindy covers the floor in blood before they get pushed into the cool room (spoofing Hollow Man). Since scene wasn't in the film, she shouldn't have the blood on the bottom of her pants. (00:55:35)

Continuity mistake: The cut Buddy has above his eye disappears later in the movie. (00:52:15 - 01:05:55)
