Fans of the classic children's book Mrs. Frisby and the Rats of NIMH were treated to animated version in 1982, retitled The Secret of NIMH. Except in the movie, there were some significant changes, like the addition of magic and mysticism, and a lot more deaths. Well, that may be rectified, since a new film adaptation of the book is in the works, one that will likely be a combination of live-action and computer-generated animation. If that had been an option back in 1982, they probably would have just done that the first time, as they would have with every other talking-animal movie made in that decade. We made a list of the animated classics that need an updated go-around, either because they didn't do the book justice or because a new version would make them that much cooler.
