I'm posting this in sci-fi/fantasy because so many sequels and prequels are of that nature. I often hear people defend them by saying that they won't tarnish the original. However, I happened to read this article which says that the MGM is suing the producers of Raging Bull 2 in part by saying it will “irreparably tarnish the value of the Picture and MGM’s rights therein.” So, here's a Hollywood studio of all things pissed that a sequel will damage the original. That's kind of rich, isn't it?
