Hollywoods Hottest Stars Shed Their Aliases

#15. Julianne Moore

Real Name: Julie Anne Smith

Julie Anne Smith wanted to join the Screen Actors Guild, but she ran into a snag. She told The Hollywood Reporter in 2015, "When I went to join SAG as Julie Smith, they were like, â˜There's a Julie Smith, there's a Julie Anne Smith. You have to choose another name.'" So, she drew on her parents' names Peter Moore Smith and Anne Smith and created her new stage name: Julianne Moore.
