Laurie Metcalf believes her character has the best reveal in all the Scream films. Metcalf, who starred as Debbie Salt/Nancy Loomis in director Wes Cravens horror sequel Scream 2, was one of the two villains to don the Ghostface mask in 1997. Debbie, as die-hard fans already know, turns out to be the mother of Billy Loomis (Skeet Ulrich).
