I'm a big fan of Disney films too. When I think of Disney films, I immediately think of the actual Disney animated features, as well as the Pixar films.
Well Disney may own licenses like Marvel, I think that films made by Disney's own animation studios are what distinguish them, and what separate Disney from other studios like Dreamworks. I include Pixar because many of it's top artists came from Disney animation.
Also, I recently bought a VHS copy of "Little Mermaid" penis edition for 25 cents at a tag sale. Looking on Ebay, they don't seem to be too valuable. It's an interesting piece to have though.
