Alice in Wonderland was based on a book that was 86 years old when Disney's film was released. It was public domain. But Disney fought hard to prevent Mickey Mouse from going into the public domain, and got Congress to extend the copyright term to 95 years. Under such a rule Disney couldn't have made Alice in Wonderland without permission from the heirs of Charles Dodgson (aka Lewis Carroll).
