Rachel Weisz @ 'Fred Claus' Premiere

British beauty Rachel Weisz (in Narciso Rodriguez) arrives at the premiere of Warner Bros. Fred Claus held at the Grauman’s Chinese Theater on Saturday in Hollywood.

In the film, Santa’s brother, Fred, is played by Vince Vaughn. Weisz plays Wanda, Fred’s soon-to-be ex-girlfriend who is on the verge of calling their relationship quits after being stood up by Fred on her birthday�”just one more example of Fred’s irresponsibility.

“Wanda’s a very down-to-earth, no-nonsense kind of girl,” Weisz has said. “She knows that Fred, deep down, is really big-hearted, but he’s like an adolescent trapped in a grown-up’s body. He’s a lot of fun to be with but also infuriating because he forgets birthdays and anniversaries. He’s the ultimate in unreliable boyfriends.”
