Diaz became a star with her first film, 1994's "The Mask," in which her personality and charm won over audiences and critics alike. Even as a 21-year-old newbie, she held her own opposite the movie's frenetic star, Jim Carrey. She also managed to steal 1997's "My Best Friend's Wedding" from under the nose of its female lead Julia Roberts. And she picked up a New York Film Critics Circle best actress award for her goofy turn as a doctor being pursued by many men in the Farrelly brothers' 1998 hit, "There's Something About Mary." Her hair "gel" scene with costar Ben Stiller is a thing of brilliance. Nothing she's done since "Mary" has been as laugh-inducing, but she's had her share of hits with the "Shrek" animated franchise, the two "Charlie's Angels" movies and the quirky "Being John Malkovich." And Diaz again demonstrates she's a pratfall master as a New York career woman who marries a working-class guy during a drunken spree in Las Vegas in the predictable "What Happens in Vegas," which opens Friday.
