Avatar has now made $512 million domestically, scored the top two awards at the Golden Globes, and is likely to be the highest grossing movie of all time. Director James Cameron should be ecstatic. And he is — as long as you don’t call his movie animated. After hearing that Meryl Streep had reportedly compared Avatar to the work she did in Wes Anderson’s stop-motion animated film The Fantastic Mr. Fox, Cameron said backstage at the Globes: “She did a voice performance for a day or two.”To prove the point that performance-capture relies on human actors just as much as computers, Cameron and Co. have put together a featurette illustrating the acting process Sam Worthington, Zoe Saldana, and Sigourney Weaver went through. It may not be enough to get these folks a Oscar nom but it should earn them more respect in Hollywood. Check out the clip below.
