The Big Empty (2003)

One of those movies which I seem to be the only one who likes. A brilliant ensemble comedy which has been out for 6 years, but is hard to find. I bought the only copy they had at my LackLuster Video store, but I don't think it saw much rental.
John Person (John Favreau) plays a down-on-his-luck movie actor in Hollywood. He has just about run out of all the money he took with him to tinsel town. One day, his reclusive neighbor (Bud Cort) shows up and makes him an offer: deliver a blue suitcase to someone known as the "Cowboy" in an isolated California desert town. If he does this he will receive several hundred thousand dollars. Of course, he's not supposed to open the suitcase.
John takes the job, travels to the town and quickly finds himself in the middle of a conspiracy involving UFOs, bullet trains, crazy locals, and the FBI. And The Cowboy isn't going to show up for a few more days.
I don't know why I love this movie, it probably has something to do with the ending. I'm not going to spoil it, but in involves the answer to human existence.
