Perhaps it's possible to convert a movie shot in that format to 2.35:1? If not, I'll go with 1.66:1 and 1.85:1, just as long as the Widescreen Image is Anamorphic and has a Theatrical Look to it :)...
I would love to see them both on DVD as well. I love Parts 1 & 2 and they deserve a good DVD Treatment. Give them both Theatrical Anamorphic Widescreen 2.35:1, Dolby Digital Surround Sound 5.1, and plenty of good extras...
