Can you please scan and digitize the whole original 1986 35mm of great mouse detective? It has the original 985 version of the Disney logo not seen in any home media and streaming release.
As you can see, the whole frame is used. I’m willing to bet that the cels not going all the way to the edge of the frame is why the full screen transfers were tighter. This is why a lot of 1.37 animated films aren’t completely open-matte.
My point was that An American Tail is open-matte, but that the widescreen has almost no extra picture on the sides, and I don’t know why.
