It's a wonderfully funny short film entitled A Fair(y) Use Tale put together by Eric Faden, professor of Bucknell University. Using various clips from Disney films, Faden explains some of the intricacies of U.S. copyright law. The last "chapter" explains why he chose to use Disney material to make his point. Very fun and very subversive.
Professor Eric Faden of Bucknell University created this humorous, yet informative, review of copyright principles delivered through the words of the very folks we can thank for nearly endless copyright terms.
