The Clown Prince of Crime
Super Freak
I believe they recently said via Twitter that they don't have "Halloween" rights anymore and that Jason was difficult to do because he doesn't have a "definitive" look.
Oh, that's too bad. Jason doesn't have a definitive look? That's silly...he looks more or less the same in most of the 80's film. They should make Jason from part 6 or 7. I would also love an ultimate Chucky figure.
