watching the CG computer graphics of the prequels in black-in-white made the effects look more realistic. I tried it and it was absolutely true- the black-and-white actually looked better.
Sorry, I don't really get it. Are you going to put all the CGI shots in AotC into black and white? Man, thats a lot of shots! That might really destroy the film - maybe some people didn't realise that the b/w shots were FX shots. Also, what about the "one element" CGI shots?
