With pretty much every super successful book, movie or TV show, someone pops up out of the woodwork to claim that it was really "their" idea, and they deserve some ridiculously large cut of the revenue. In the case of the movie Kung Fu Panda, we've already seen at least two different people claim credit. The first one has gone to trial... and lost. The jury actually found that Dreamworks had entered into an "implied" contract with writer Terrence Dunn... but then also found that they didn't actually use any of his ideas, so it didn't matter. These kinds of lawsuits really are nuisance suits, but rather than go back to obscurity, Dunn has already announced plans to appeal.
