Avatar premiers at Odeon Leicester Square in London

Sam Worthington shows off his scruff at the premiere of Avatar at the Odeon Leicester Square in London.

The 33-year-old Australian actor brought along his girlfriend, Natalie Mark, and posed for photos with director James Cameron and co-stars Zoe Saldana and Sigourney Weaver, who planted a kiss on him!

Sam recently told reportersu00a0 how he landed the role of Jake Sully:"James Cameron phoned me up and I was having my breakfast," Sam said."He said, 'Do you want to work with me?' And I went, 'It's about time you asked! Do you want to work with me is more to the point.'"And he said, 'Yep. How quick can you get out here?' I said, 'I need a week. I've got to fix the brakes on the car.' He laughed and said, 'That's my boy."
