Booshman said:For Superman III, the extra footage is only available in 4:3 and pillarboxing that footage to fit the original aspect ratio cuts off too much image to be worth watching for me.
You don’t have to cut off any of the image. The 4:3 footage can be pillarboxed and letterboxed. This is what I was trying to explain before. I’ve seen it done, and it works better than you might think. (But, of course, I understand that some people don’t like it.)
