How Thomas became Tom Cruise
Unlike most stars on this list, Tom Cruise didn't invent a new name. He was born Thomas Cruise Mapother IV, the fourth generation of the name. His father, an electrical engineer, was Thomas Cruise Mapother III.
Professionally he simply dropped the surname: "Tom" from Thomas, and his middle name moved to the end. He made his film debut in 1981. Plenty of websites say "Cruise" was chosen because it sounded fast or cool; the name was already on his birth certificate.
