CHALLENGE OF MAKING TRON: LEGACY (2010)

when they're working on the second movie, they couldn't just replicate the effects of the first movie because computer graphics had come so far since. people's expectations for computer graphics were at a much higher level. They have to maintain style of the first movie while giving everything a significant upgrade and visual appearance.

unlike the first movie, they filmed a lot of stuff practically on real sets with real costumes. they got to have lights in the suits. they did digital scans of the main actors and took those scans and built the cg suits around them so they're able to weave in all light designs

one of the biggest challenges of this movie was filming everything in stereoscopic 3d with a two-camera system. having one camera

pointed forward and another camera pointed through a mirror slightly offset to give you that inner pupillary distance of your eyes.
