'Scream 4' Cast Make Their Case For Why They're NOT The Killer, But Do You Believe Them?

"Scream 4" arrives in theaters this Friday, and with Wes Craven's newest nightmare comes a new killer wearing the Ghostface mask. But who exactly is the knife-wielding maniac beneath the hood?

Don't ask the cast of the latest "Scream" sequel — those guys are sworn to secrecy. But that doesn't mean they won't give you impassioned arguments for why they're not the killer.

We spoke with several of the "Scream" cast members and asked them why the audience should believe that they're not responsible for slaughtering their fellow actors in the series' impending reboot. What we received in turn was a healthy mix of compelling logic, mysterious questions and even some not-so-convincing arguments over why they're not the latest "Scream" killer. Watch their pleas in the video below and click past the jump to read what they had to say.

Hayden Panettiere: "My character is not the killer, because she knows horror movies too well … she knows how they work, and she's too terrified in that scene in the preview."

Anthony Anderson: "I can't do it because O.J. already did it."

David Arquette: "I'm not the killer… because I am the killer!"

Adam Brody: "My guy is just kind of a dummy. … I could be putting everyone on, but I don't think I have enough screen time to totally be the killer — but maybe?"

Courtney Cox: "My character's not the killer—because maybe she is!"

Neve Campbell: "My character's not the killer because she's Sidney Prescott."

Emma Roberts: "My character Jill is not the killer because she's Sidney's cousin — hel-lo!"

Aimee Teegarden: "Why am I not the killer? I'm not the killer because I have great hair in the movie. And if you have great hair, you don't die — bottom line!"
