Harrison Ford* in a cemetery scene. We were working in freezing rain and the extras holding area was an unheated tent whose flaps kept a-flapping in the wind. He walked off the set and told the director he wouldn’t shoot another scene until we got a heated non-flapping tent. We got one. Nobody messes with Harrison Ford.
Bear in mind that when it comes to movies ‘worked with’ usually translates to ‘got to stand near him in a scene.’
