Matthew Lillard and Skeet Ulrich addressed one of the long-standing mysteries in the “Scream” franchise Saturday: Who was in the Ghostface costume when Tatum Riley (Rose McGowan) was killed? “To be honest, not even [screenwriter] Kevin Williamson knows who killed [Tatum]. And he wrote the damn thing,” Ulrich, who appeared alongside original “Scream” stars Lillard, Jamie Kennedy, Joseph Whipp, as well as stunt actor Lee Waddell and Ghostface voice performer Roger L. Jackson. This wasn’t the only behind-the-scenes tidbit shared during Saturday’s panel, as Lillard and Ulrich recalled how demanding the final sequence of the movie was to film.
