Now, it seems things have changed. Judging by a Tweet from Williamson himself, it appears that perhaps the scribe has written a draft for Scream 5 and is very much interested in returning (amazing what a few months away can do). But -- do the Weinsteins want Kevin's script? The answer appears to be no. And that's a damn shame.
Thanks to our good pal Mr. Klyza over at Scream-Trilogy.net for pointing this out to all of us. I don't care if Kevin wants to send Ghostface to space, if Kev writes it, I'll watch it!
