Factual error: At the end of the film, the police just let anyone walk around the crime scene: in addition to the caller you also see various tourists gathered around the phone booth. The police would never ever do this: as Leon the pimp was murdered right by the phone booth it is a crime scene and as such must be cordoned off for the forensics team to arrive, instead of letting people contaminate the crime scene. Even though the police "know" the pizza guy did it, they still need to look for forensic evidence.
Phone Booth (2002)
Plot summary
Directed by: Joel Schumacher
Starring: Colin Farrell, Kiefer Sutherland, Forest Whitaker, Katie Holmes, Radha Mitchell
Genres: Thriller
Stu is an agent for people wanting to get famous in New York city. You see him and think he's all high and mighty, like he is the greatest person on earth, but truth be told, his life isn't so glamourous. He enters a phone booth to call one of his clients - who he is using to cheat on his wife with - and they flirt a bit. Then, as Stu gets out of the phone booth, it rings. Stu of course answers it and is stuck in the game of an insane sniper. A ringing phone has to be answered, doesn't it?

The Caller: If you have to ask, you're not ready to know yet.
Trivia: This movie took only 12 days to shoot. The scenes inside the phone booth were shot in 10 days and the exterior shots were taken over the other 2 days.
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.
