Continuity mistake: In the scene where the pimp starts shaking the phone booth, ad cards and Stu's wedding ring are visible on top of the phone. After the "shaking" the ad cards and ring are gone. A few minutes later the ad cards are back, mixed in with the broken glass. (00:25:15)

Phone Booth (2002)
Ending / spoiler
Directed by: Joel Schumacher
Starring: Colin Farrell, Kiefer Sutherland, Forest Whitaker, Katie Holmes, Radha Mitchell
Genres: Thriller
Stu manages to survive his ordeal while he identifies the caller as the man who tried to deliver him a pizza in the beginning of the film. It turns out the caller is still alive and he pays Stu a visit while he is in the ambulance. He lets him live but promises he'll be back if Stu loses his new found honesty. And then a phone rings.

The Caller: If you have to ask, you're not ready to know yet.
Trivia: The phone that Colin Farrell (Stu) was hooked up to actually had a person talking to him, to keep him sane during the confining shoot.
Question: Are the pizza delivery guy and The Caller two different characters? I was always under the impression that they were one and the same.





Answer: The pizza man is intended by the Caller to be a decoy so he can get away. The Caller sends the pizza man to the phone booth so that Stu will identify him later in the apartment, giving the police a convenient answer to the mystery while the real Caller escapes. In fact, at the end of the movie, the Caller comes to visit Stu - obviously he's not the dead pizza delivery man.
