Julia Roberts has one man to thank for superstar career—her Pretty Women director Garry Marshall. "He's one of my favorite people in the world—he took a chance on me when it wasn't the easiest decision to make," the actress told WWD. So it was a no-brainer for the actress to join the star-studded cast of Marshall's upcoming film Valentine's Day. "It's insane the people that are in the film!" The cast includes Bradley Cooper, Jennifer Garner, Taylor Swift and Jessica Alba, just to name a few. "This movie is just about people loving each other and missing out and getting it right, and it's pretty incredible," she said. Valentine's Day hits theaters February 12th.
