Well supposedly he's an "executive producer" but if you ask me I think that its another one of those "Wes Craven presents" things somewhat like in Dracula 2000.
I think its more along the lines of Dracula 2000 and the Project Greenlight folks wanting his input as he is considered *wrongly imo* as the master horror director the US has.
Craven is a master don't get me wrong, but we got quiet a few Masters but I think only TCM with Tobe Hooper is most widly known or John Carpenter with Halloween.
