In case you don't get it - the Light-cycle rider in yellow is CLU!! CLU is Flynn's program/alter-ego in the world of the computer who was also played
by Jeff Bridges in the original TRON. Just as TRON himself was Alan Bradley's program/persona (Played by Bruce Boxlietner).
Thing is - this is the YOUNG Jeff Bridges that we are seeing as CLU now.
From the few seconds of footage there that is available of his face, I have the following theory:
They are likely using a similar system to that used in Pirates of the Carribean and in Superman Returns of facial mapping (Davy Jones and Jor-El respectively).
There's plenty of footage and records of Jeff Bridges in the 80s, so they are using that data to build a contour map of his face. Then they are using a
facial mapping system on Jeff Bridges as he portrays CLU, so that they are then able to insert the younger face over the older one (or over a stunt player) and
his performance is retained, he simply now has the young face of his 80s self as his persona.
