Question: I was watching this film on TV the other night, and was expecting to see the train crash at the start, so I was surprised when I didn't. Has this been cut from the TV version?
Question: Why are there so many things that are upside-down in this movie? What is the significance of it?
Answer: Everything related to Samuel L. Jackson's character is upside down - to give a hint about his role in the movie.
Question: When David touches the guy in the stadium he feels that he is carrying a gun but when he actually checks him he doesn't find one. Why?
Answer: I believe you are confusing the man with the gun with the man with the drugs. The man with the gun is never searched because he steps out of line and walks away. The man with the drugs (who is played by director M. Night Shyamalan) is searched for drugs, but David doesn't find any. Either he had the drugs in the stadium at a previous game or he sold/passed them along to someone else before David bumped into him.

Question: Why exactly does the janitor hold that family hostage? What is the point?
ModestFilmCollectorChosen answer: He's a murdering rapist. The point is he's evil.
JC FernandezQuestion: When David uses his power to see into people's lives, what exactly does he see? They go by too fast.
ModestFilmCollectorChosen answer: When he touches someone who has or will commit an evil act, he sees the act. For example, he sees a racist man throw something at a black woman for no reason, he sees someone buying drugs, he sees a woman kill another woman.
Answer: No, the crash never actually happened on-screen.
