sequelits, the need to make sequels. Basically because they usually have a happy ending, they have to come up with another story to keep making money on the characters. Victor Hugo would most likely get ill at what they did to his characters that he wrote about in his book.
plus because they renewed the Characters of Peter Pan, Cinderella, and the Hunchback, they can keep the copyrights going. I think at one time they almost lost the rights to Whinnie The Poo and others?
But anyway, why make a totally new movie when you can just recycle the old ones and make a new one based on the old ones?
Disney did this before to Aladdin, The Rescuers, and others.
Maybe they can change the ending of "Old Yeller" and make a sequal out of that?
P.S. Don't forget Balto II, it is out as well.
