Cameron Crowe
Cameron Crowe is not known for showing up on the screen, but he made a special exception for the film Minority Report. Minority Report was actually a Steven Spielberg film, but the duo had made a deal years before. Steven Spielberg had appeared briefly in Crowe's film Vanilla Sky starring Tom Cruise. Years later, the directors swapped spots. Crowe plays a passenger on the train who might end up recognizing Cruise as a precrime leader on the run.
