The Scream franchise has experienced many casting - and story line - changes, but even the most die hard fans may be surprised by what could have been for the beloved horror films. Journalist Ashley Cullins spoke with the cast, creators and crew from all seven Scream iterations for Your Favorite Scary Movie: How the Scream Films Rewrote the Rules of Horror, highlighting behind-the-scenes insight and revelations about the making of each installment in the horror franchise. Scream, released in 1996, focused on Sidney Prescott (Neve Campbell) as she faced off against numerous killers hiding their identity behind the infamous Ghostface persona. In the film, she received help from fellow OG Scream characters Gale Weathers (Courteney Cox) and Dewey Riley (David Arquette), which led to the creation of three sequels in 1997, 2000 and 2011. The franchise was revived nearly a decade after Scream 4 was released, allowing Scream to introduce fans to new protagonists Sam (Melissa Barrera) and Tara Carpenter (Jenna Ortega). With changes came surprising exits, including Campbell's decision to part ways with the franchise after filming the fifth installment due to failed salary negotiations. (She returned for the seventh movie after Ortega, 22, left due to scheduling and Barrera, 35, was fired after being vocal about her support for Palestine amid the ongoing conflict between Israel and Palestine.) Scream's All-Star Cast Through the Years Cullins' tell-all featured never-before-revealed details on who else auditioned for key roles and initial ideas for Scream plot lines.

Dimension Films/courtesy Everett Collection According to Your Favorite Scary Movie, Brittany Murphy and Alicia Witt were in the running for Sidney, while Natasha Lyonne and Marley Shelton auditioned for Tatum and Brooke Shields for Gale. Barrymore, who was initially meant to play Sidney, ultimately took on the role of Casey, though Alicia Silverstone was also eyed for the part. Jeremy London, James Marsden and Vince Vaughn were on the list of actors who also auditioned. Hiding Henry Winkler's Involvement in 'Scream' While Barrymore was promoted to have a larger role than she actually did, Winkler's appearance as Principal Arthur Himbry was downplayed. "I distanced myself a little bit because an executive from the movie company said, 'We're not gonna put your name on the movie. You were the fonz and that's gonna knock the balance of the horror off. We can't put your name on the one-sheet," Winkler shared in the book. "Apparently, they showed the movie to the audience for tests and I got applause when I walked on the screen." He continued: "The same executive came to me and said, 'Would you do press for the movie?' I said, 'You didn't even put my name on the movie and now you want me to do press?' Ah, show business. It all works out in the end. Here I am, twenty-seven years later, signing posters of Scream everywhere I go. So, I finally got my name on the one-sheet." Figuring Out the Killer in 'Scream 2' Courtesy of Paramount Pictures and Spyglass Media Group The sequel unmasked Laurie Metcalf's Nancy Loomis as the killer, which was always the plan. But her accomplice changed a few times between Derek (Jerry O'Connell) and Hallie (Elise Neal) before Mickey (Timothy Olyphant) was chosen in the "only version of the ending ever actually written" for Scream 2. Scrapping Plans for 'Scream 3' "We had a really cool idea of what the third movie should be, and we were really excited about the concept. Then Columbine happened. That basically threw out the general idea of what Scream 3 was going to be," producer Julie Plec revealed, describing how the 1999 Columbine High School massacre influenced the film. Was Dewey Ever Meant to Be the Killer? Arquette's fan-favorite character was involved in taking down Ghostface for five movies before his brutal death. But according to Your Favorite Scary Movie, Dewey being involved in all things Ghostface wasn't always off the table. "David, my assistant, wrote a decoy script where Dewey was the killer," Williamson teased. "I sent it to a friend of mine who had a Halloween blog, or something, and he leaked it in some other state. So, it looked legit. We thought if that one leaks first, then if the real one does leak no one's gonna care. So, that one got leaked by design and it has created this folklore that Dewey was the killer. Well, in one version he was, but not in the version we were filming." Being Conflicted on Who Would Play Jill in 'Scream 4' Dimension Films/courtesy Everett Collection Scream 4 coproducer Carly Feingold said it was "the hardest to cast" Jill, because the creative team found themselves conflicted between Emma Roberts and Hayden Panettiere. It was ultimately decided that Panettiere would portray Kirby instead "to bring her back" after the actress' contract "specified
