Continuity mistake: Just after the doctor started the post mortem on that little girl, the front of his gown is covered with blood. Yet, a few seconds later, after the two other guys appeared, his gown looks better, with less blood. And during the whole post mortem scene, the blood spot actually changes its size a few times.

Trivia: Originally, the movie was going to be shot by cinematographer Jordan Cronenweth, but Cronenweth suffered Parkinson's Disease midway through filming and was let go by the line producer, being replaced by Alex Thomson. However, impressed by Cronenweth's work, David Fincher later worked with Cronenweth's son Jeff in nearly all of his future movies, resulting in two Academy Award nominations.
