While promoting his new show The Vampire Diaries this week, Kevin Williamson confirmed his work on a fourth installment of Scream.
At the moment, the writer doesn't envision Neve Campbell taking part in Scream 4, but he told IGN:
I've been hired to write it. I'm concentrating on the first twelve episodes of Vampire Diaries, and thank god I have the time, because Courteney [Cox] and David are returning, but Courteney's show [Cougar Town] got picked up. And so we won't get to film until the next hiatus, which is good for me. So I can actually have fun writing it. I'm half way through it.
Williamson also said director Wes Craven won't commit until he sees a script.
