The stars of Avatar hit the blue carpet in LA last night to celebrate the Golden Globe nominated epic 3D film before it hits theaters this Friday. Director and writer James Cameron was on hand alongside stars Sam Worthington and Zoe Saldana. Sigourney Weaver was also there along with her two daughters. Audrina Patridge spent a good chunk of yesterday filming for her upcoming show, but she was able to put on a poufy jacket just in time for the screening. The cast moved on afterwards to a special bash at David Arquette's Propr store, where they mixed film talk with humanitarian efforts to benefit the Save Darfur organization.
