I'm sure this has been discussed, but it deserves some attention for the release of ROTS.

I find it a trifle annoying that lightsabers act as light sources for CG characters (mostly Yoda) but for the live action characters, they almost never do (do they ever?). I always thought it was weird that the lightsabers didn't cast any light in the OT, but I'm more annoyed that they reflect off of Yoda's skin and nothing else. This seems like something the art directors would have thought of. I wonder why the issue remains ...
