Continuity mistake: Early in the movie, there is a black clock on the wall in Dan's kitchen that reads 7:50. Later, when he is in Alex's apartment strangling her, the same black clock is now in her apartment and it, too, reads 7:50.

Revealing mistake: In the first scene where we are introduced to Alex Forrest at the bar during the cocktail party, she is almost always smoking cigarettes that are not lit. She continually dashes out ashes that aren't there and there is never any smoke coming from the cigarettes.
