Where She's From: Australia
Though the "Bridesmaids" star sounds as American as they come on film, she's actually a girl from Down Under. But when it came time to film "Neighbors," Byrne's character wasn't hiding her accent. The 36-year-old actress was skeptical at first, saying, " Initially, I thought it would be too jarring. Then I thought it could work for the character, because Australians tend to have a wild streak." Since Byrne is currently filming "Neighbors 2," it sounds as if she was right.
