The Bugonia star was forced to change her birth name when she became a working actress, but the process wasn't a smooth one. Emma, whose real first name is Emily, recently told The Late Show with Stephen Colbert she had originally landed on the name "Riley". "I actually adopted a stage name for, I would say, like six months. Because the Screen Actors Guild, it's like the Business Bureau. You can only have one person with that name," Emma, 36, explained. When teenage Emily first attempted to register with the guild, she discovered there was already an actress registered under the name "Emily Stone".
