Continuity mistake: During the interview with Detective Kimball, the pen in front of Patrick is on a notepad and faces him with a clip when the camera is above Christian Bale's shoulder, but it's directly on the leather blotter. (00:33:25)
Continuity mistake: The label on the Apollinaris bottle changes orientation between shots during the first visit of the detective. As Linda sets it down, the label faces away from the camera; in the immediate close-up, it is facing forward in a clear product placement shot, only to face away again in the rest of the scene. (00:33:40)
Continuity mistake: At the Xmas party, someone puts plush antlers on Patrick's head while Evelyn shows him her new pet Vietnamese pot-bellied pig. The antlers are in front of Christian Bale's ears. He excuses himself to go talk to Paul, and the antlers are now behind his ears. (00:24:00)
Continuity mistake: We see Patrick dial the number of the elusive Dorsia restaurant for the first time; a noticeable long lock of hair dangles in front of his forehead. In close-up (when he is laughed off over the phone), his forehead is clear, no wisps in view. (00:15:25)
Continuity mistake: When Patrick calls Courtney to invite her to Dorsia, the porn he is watching on tape is supposed to be "Inside Lydia's a55" (well, I can't post the naughty word here; you get the idea). The case turns around in Patrick's hand between shots. (00:14:55)
Continuity mistake: Immediately after Patrick asks his secretary for mineral water, he is holding a filled glass at the bottom of the frame. The glass appears before she has even had a chance to move, let alone fetch it for him. (00:08:25)
Continuity mistake: Patrick casually puts his Walkman on the desk as he enters his office for the first time in the movie. The Walkman and headphones are in a different position in the next shot before he had a chance to touch anything. (00:07:45)
