The Lawnmower Man

I found this article interesting on the lawsuit King filed to have his named removed from the Lawnmower Man. http://everything2.com/title/The+Lawnmower+Man

King lost the suit, but producers still removed his name. Somehow the movie got a sequel -- go figure.

Here's what I don't understand: They can make a movie of Lawnmower Man, and even give it a sequel, but no Eyes of the Dragon?
