If the source is right, 4 will jump into production early this year, "re-starting" the franchise, but adding in some old characters. It seems that Jamie Kennedy told iFMagazine that he might reprise his role, and that "the rest of the cast would be a mixture of new characters with 'old faces that you wouldn't believe,' and that the film will only go ahead with the involvement of director Wes Craven." As of December 13, writer Michael T. Kennedy was still waiting to hear from the Weinsteins about whether his script was a Go.
I'm not quite sure how you reboot the franchise, include the original characters, yet focus on new ones. Was there another killer out there while Billy and Stu sliced and diced their friends? Is Sidney not the only girl in Woodsboro to attract vengeful murderers? What faces will return? I've always wished for a Scream franchise where Randy and Tatum were the ones who got to live, but I think that ship has sailed.
