Continuity mistake: After the dinner scene, Julia goes up to the attic and the shadow she casts on the door changes twice between cuts. We get a POV shot of her approaching the door, and right before it cuts, we see a teeny bit of shadow appear on the door (from Julia approaching it). It then cuts to a wideshot, and there's instantly a LOT more shadow on the door. Then a few seconds later, the shadow on the door changes again during the closeup of her turning the handle - there's suddenly much LESS shadow.

Continuity mistake: When Bill kisses Julia on the cheek as she's about to step away, he puts his hand on her arm, right under her shoulder. When it punches in to a medium shot from the wide, his hand is no longer there.

TedStixon

Continuity mistake: During the dinner scene, when Julia stands up to leave, as it cuts between her and wider shots of the table, the expression on her face and the direction she is facing subtly changes a few times between cuts.

Audio problem: When Kirsty is flirty with Steve at dinner and he says "So lay down," the audio doesn't QUITE match his lip movements. (Several characters were redubbed with American accents in post. Presumably this is the reason for the inconsistency).

TedStixon

Continuity mistake: When Frank is being resurrected, and his "torso" lurches forward and attaches to the brain, the shape and position of the brain, and the amount of goo on it changes twice between edits.

TedStixon

Continuity mistake: When Frank is being resurrected, when the arms first lift the barely-formed "torso" off the ground and it cuts from a medium to a closeup shot (where we see a closeup of the two little "tendrils"), the amount of goo/slime/blood on the torso changes between shots. A lot of the goo/slime/blood instantly vanishes between cuts.

TedStixon

Continuity mistake: When Larry comes to the attic after cutting himself, the amount and pattern of the blood on his hands/forearms changes slightly when it cuts to the wide, high-angle shot.

TedStixon

Continuity mistake: After Larry cuts his hand, he goes the attic, and we get three closeups of blood dripping onto the floor. Two problems. Larry starts to walk forward at one point, but we get another closeup of the blood hitting the SAME spot on the floor, which makes no sense... it should have dripped in front of the puddle since he moved. Then, Larry walks all the way across the room, and we get a FOURTH closeup shot of blood hitting the SAME spot, even though that spot is a good 12' behind him at that point.

Continuity mistake: When Kirsty first enters the house, she pushes the mattress in the doorway up to squeeze by. In the first shot, it's only about 3-5" over her head... but in the next shot, it's suddenly about a foot higher in the air.

TedStixon

Audio problem: When Kirsty enters the house and the moving man says "My lucky day!" his words don't quite match the lip movements, making it obvious the line was dubbed in post.

TedStixon

Continuity mistake: When Kirsty first arrives at the house in the beginning, she stands outside for about five seconds. If you pay attention, her hair changes when it cuts from behind her, to the front, then back. (In the shots behind her, her hair is going straight down over both her shoulders, whereas in the front-facing shot, it's pulled off to only one side).

TedStixon

Deliberate mistake: When Larry and the two moving men are first bringing the mattress through the doorway and it gets "stuck," the camera placement makes it pretty obvious that the mattress isn't really stuck. There's far too much wiggle room on either end for it to be "stuck." (Obviously it needs to be stuck for the scene to work... but still a weird inconsistency).

TedStixon

Continuity mistake: When Larry goes to get beer for the moving men and Julia walks by them, the directions they are facing and the looks on their faces change slightly between cuts.

TedStixon

Other mistake: The film is meant to be set in the US, but there are some odd lines of dialogue that seem to indicate the movie takes place in the England, such as a reference to the (very British) Julia being on her "home turf." This is the result of a change made in post-production, where producers decided to change the setting to the US to make it more marketable to American audiences. Unfortunately, there were some lines about the original English setting that (evidently) couldn't be cut around.

TedStixon

Audio problem: When the unnamed Asian man sells Frank the box at the beginning, watch when he says the line "it always was." The words don't quite match the lip movements, revealing the line was looped in post.

TedStixon

Revealing mistake: When Frank is solving the puzzle-box in the opening scene, you can pretty blatantly tell when they switch out the prop, because little lines, gaps and shadows appear on the box that weren't there before. (Since it wouldn't be possible for a single prop to do all the different "functions" of the mystical box.) It's most noticeable when the first moving part appears, and you can see several hard "lines" that weren't there in previous shots.

Trivia: The film was originally meant to be set in England, but this was changed during production when the studio decided it should take place in the US. In order to help sell this, a number of the English cast members were redubbed with American accents. However, as the decision was made after part of the film had already been shot, there are a few lines alluding to it being set in England still left in the finished movie. (They evidently couldn't be reshot or cut around).
