Continuity mistake: When the panel of doctors are being queried by Aames, for the second time of the loop of this interview, the black box containing the mask can clearly be seen in the bottom right hand corner on the desk when the camera swings to the main doctor. When the camera pans back again, it is gone, and it is only after this that the assistant brings in the box.
Continuity mistake: In a scene during David's birthday party there is a sequence showing Julie and Brian talking on a sofa with a blank white wall in the background. Later, in a different scene showing Julie dancing with one of the waiters holding a tray of martinis in front of the same sofa, there is a black and white picture of a car in the background.
Continuity mistake: In the scene with David's birthday party, he comes downstairs after being with Julie, and is talking with Sofia about how Julie is stalking him, when Julie is staring at them, her part in her hair goes from being on the left side to being on the right side, then back again.Melissa
Continuity mistake: When David and Sophia go upstairs to his friend's apartment, his friend walks in. When he is talking to David in this scene, in one shot David's hair is perfectly normal, and then there is a shot of his friend, but when it comes back to David his hair is abnormally messy and sticking up. In the next shot of David it's back to being flat again.
Continuity mistake: When David comes back to Sophia's apartment, towards the end of the film, he rips the photos off the fridge. But in the next shot, when he is throwing something to the wall, the photos are still on the fridge.
Continuity mistake: Tom leaves the bar after wearing the mask in public for the first time. He and his best friend have a argument outside in an alley. As they cut to and from Tom his hair is hilariously out of whack on one of the shots.
