From the set of 'King Kong': Digital doubles

The 'King Kong' crew posted another video blog entry last week. It delves into the process of creating digital doubles for each of the film's lead actors, to be used for dangerous stunt sequences...and sometimes to be inserted into computer-generated environments where the standard "green screen" technique might not look convincing.

Director Peter Jackson says, "Of course, digital doubles will never replace actors. That's the big fear, and I think it's a lot of old nonsense, really... Digital people don't have hearts and souls, and they can't provide everthing that an actor can provide in a performance."

Besides, if you're in a position to cast Naomi Watts and spend a couple months on set with her in New Zealand, why would you choose a digital double over that?
