Sam Worthington and 'Avatar' Stars Cover 'Life'

Sam Worthington and his Avatar co-stars Zoe Saldana and Sigourney Weaver take the covers of special collectors’ editions of Life!

The 33-year-old Australian actor, his castmates and Avatar director James Cameron gave Life an exclusive backstage pass for four days during a jetset promotional tour around Europe.

“The jet from Paris to Berlin was a blast,” Life photographer Jeff Vespa said. “Everyone was giddy and goofing around….James Cameron fed Sigourney grapes. Everyone drank champagne and took cameraphone pictures of each other.”
