What is Tom Cruise's real name?

The answer is: Thomas Cruise Mapother IV. No matter how fast he runs, Tom Cruise can’t escape his true name of Thomas Cruise Mapother IV. Really, Tommy was dealt a terrible hand with that name, and it isn’t even his fault. He’s the fourth generation in his family to be burdened with that mouthful of glass of a name. No matter how good looking he is, there’s no way Tom Mapother IV would become a household name, so the change was a good call.Source
