A friend of mine manages a Hollywood themed museum located in the Hollywood Casino in Pennsylvania. They recently put a couple vintage bikes on display that are "studio representations" (replicas) including Marlon Brando's own 1950 Triumph Thunderbird as seen in "The Wild One". Triumph's importers originally objected to the bike being used in a film about rowdy motorcycle gangs. The Steve McQueen motorcycle is a studio replica of his "Great Escape" Triumph, which was dark green in the movie. Also, I don't remember the Indiana Jones sidecar bike seen in "The Last Crusade", having mag wheels.
