Directed by: D.J. Caruso
Starring: Kiefer Sutherland, Ethan Hawke, Angelina Jolie, Gena Rowlands, Tchéky Karyo, Olivier Martinez
Plot hole: Most of the story depends on Costa coming forward as a witness; however, he would have had no reason to do this. It would only make his goal of assuming others' identities more difficult.
Suggested correction: Some serial killers try to involve themselves with the investigation, for instance famous serial killer Ed Kemper.
Continuity mistake: When Angelina pulls up in front of Ethan's apartment she hears 4 shots from inside. During the replay, when the viewer sees how things really happened, there are 5 shots. (01:10:25 - 01:31:20)
Paquette: What kind of gun did he have?
Costa: He had the kind that leaves really big holes in people.
Trivia: Even though he shares top billing with Angelina Jolie and Ethan Hawke, Kiefer Sutherland is on screen for less than three minutes.
Question: When Ethan Hawk takes a new life, does he have to shave his fingerprints/get plastic surgery/new teeth etc. because when he started he looked way different than the present day Ethan.
Answer: Yes, he must do this to truly feel like the different person he is trying to be. Also, so the police won't suspect anything if his traits don't match his identity.
