TROLL IV: Harry Potter vs. the Troll

(In a bizarre twist MGM might be able to do this; the 1st Troll movie was about a kid named Harry Potter rescuing his sister from a Troll.  J.K. Rolling even admitted in the 1st book's 1st chapter that the name was common.  At the very least the lawsuit would be interesting.)
