Continuity mistake: Glenn Close's outfit changes four times during the same courtroom scene, while she is giving her opening statement in front of the jury.
Continuity mistake: At the end of the film when Glenn Close shoots Jeff Bridges you can see the blood splatter hit the ottoman at the end of the bed. A few cut shots later the blood has disappeared.
Factual error: Peter Coyote describes the killer as "not a psychopath. He's an ice man," implying the killer is too calculating and manipulative to be considered a psychopath. This is a common misconception: a cool and calculating manipulator is exactly the standard profile for a psychopath. Most people who make this mistake are usually conflating psychopathy with psychosis (or being "psychotic"), when those are actually two separate and quite different conditions.
