Scribe Kevin Williamson tells MTV News he's busy finishing up the script for the fourth "Scream" film and a fifth one is already being planned which he's signed to write.

"The fourth one is an ensemble. It'll take place right now, 10 years later, and it's going to take place in [Sidney Prescott's hometown of] Woodsboro. We'll have our three main characters, and we'll be introducing several more" says Williamson.

He adds that those 'several more' will essentially be the stars of this new trilogy - "We'll also be introducing a little group, a little ensemble of new castmembers. That'll take us through the next three."

Stars Neve Campbell, Courteney Cox and David Arquette are all set to return and Wes Craven has expressed interest but hasn't committed as yet.
