Shooting for Tron 2.0 is underway.
According to sources, Disney flew Jeff Bridges to Canada for a unique digitization process that will "de-age" the actor by 27 years for the sequel.
Bridge's character from the original Tron, Flynn, is set to interact with his younger self in the follow-up, as early scenes from the movie show him watching over the young Flynn racing.
This technique - also used in X-Men: The Last Stand to knock 20 years off Patrick Stewart and Ian Mckellen - involves plaster-casting Bridges to create a 3-D model; then sculpting a younger version of his face to be super-imposed onto a body double.
Tron 2.0 will be released in the summer of 2011.
