Rumors are swirls about all what exactly is happening with Scream 4. Since the beginning of the year talk has said run the gamut from rumors who might return (see the original post here for more info).
Now director Wes Craven has spoken out to website Bloody Disgusting, while promoting the remake of The Last House on the Left. About returning to the series he said, "It would take it being really as a good a script as the first one was and the pay day reflects what I've done for that company and what I've gone through on Cursed."
Craven does confirm that writer Kevin Williamson is working on a script currently.
