This is a 35mm teaser trailer for the 1986 animated Disney film The Great Mouse Detective. It was scanned at 3K resolution (scaled to 4K for YouTube to avoid compression) and is completely open matte, unlike its release in which it was cropped to the cinema aspect ratio. Because of that, what you see here is the full 35mm frame. Nothing else was done to alter the trailer, besides encoding and rescaling for YouTube. Because of that, the trailer print is in its natural state.
