I understand he's a script doctor now. Tweaking and improving other peoples work.

Also, when they fired him from TWD, he sued their bollocks off. He now has more money than he knows what to do with.

But you are right. He was such a good director that if he were to release another film I'd be all over it like white on rice and a glass of milk on a paper plate in a snowstorm (credit to Major Payne for that)
