Tom Cruise and William Mapother
This would be more obvious if Tom went by his birth name, Thomas Cruise Mapother. Not only are they related, but the “Mission Impossible” star has even helped the “Lost” actor. “Tom has been kind enough a couple of times to suggest to a director, ‘If you’re looking for an actor, why don’t you audition this guy?'” Mapother said. “So it has opened a couple doors, but it hasn’t gotten me any roles.”
