In this video, Discovery News takes you behind the scenes of TRON Legacy to give you a peek at the technology digital artists used to remove twenty years from Jeff Bridges' face.

Similar to the techniques used for the movie Avatar, the face-replacement technology leaves some worried that actors will be obsolete. But actress Olivia Wilde, who played Quorra in TRON Legacy, isn't worried about the new technology. She believes actors will always be needed. "The rig that Jeff wore wouldn't do anything if it weren't for his amazing performance inside of it," she said.
