Bradley Cooper and Renee Zellweger Love Being Co-Stars

They've paired up in real life, and now they're starring together on the big screen. Renee Zellweger and Bradley Cooper were thrilled to work together on the set of their movie Case 39, which will be released in theaters on Friday. The couple met on the set of the film, which was shot in late 2006, though they did not begin their relationship until 2009. The movie's release was delayed for years, but after its success in other countries, Paramount gave it the green light.

The movie is a spooky thriller centered on a little girl named Lilith who is haunted by supernatural forces. Zellweger plays Emily, the social worker who first tries to protect Lilith, while Cooper plays Doug, the psychologist that Emily turns to for help.

"He's a great actor, great actor. I just got so excited, not believing that I was going to go to work with him," Zellweger, 41, told Entertainment Tonight of Cooper, 35. The actor returned the praise, gushing over her talent. "Can't say enough about her," he said. "I never met her before this movie, but I just love her. I love coming to work. I love acting with her. I can learn so much from her." –AMY LEE
