I know what you mean about the video being more matted than you saw it in the theatre. As I mentioned before, the same thing happened with Pursuit of Happyness.
I didn't mention James Cameron's films because I already knew about them. The list I wrote was ones I don't know about. Some might not be matted, I don't know.
Willy Wonka (from the 70's) is another. The back of the warner dvd says it is not matted but I have the full screen version and, honestly, it didn't look like I was missing anything.
