Saddest thing about Tron Legacy CG characters is that noone seems to remember or even have noticed the CG Bruce Boxleitner: http://www.danplatt.com/?p=187 Completely convincing. I really hope we're gonna get a sequel with that character...
Yeah that's pretty nuts for on a face in a CG film, since CG films love to zoom in on faces waaay more than for a liveaction actor. Also, altho minor, the UVs on Don's purple eyemask is pretty sloppy for a prominent camera area of a face aswell.
