OTOH, Disney is aggressively pushing trademark where it hasn't gone before. For example, they're asserting that "Movies about Snow White" are a thing only Disney can do, because "Snow White" is a trademark. I could absolutely see Disney saying "That clip of Steamboat Willie is a trademark of Disney Animation Studios. If you use that in animation, you're diluting our trademark."
