Glad to see this officially in the works. I brought it up earlier in the month on Horror News, but from what it seems; this is apparently going to be a horror film potentially set in the DCU (The closest comparison we could make is Swamp Thing).
Assuming this is part of the DCU proper, then that should mean we finally get to see Alan Tudyk lead a horror project in a promiment way (especially as the character is in Creature Commandos).
