Trailer! More Screams in 'Scream 4'

Original "Scream" stars Neve Campbell, Courteney Cox and David Arquette reprise their roles in "Scream 4." It's been 10 years since Sidney Prescott (Campbell) was stalked by the Ghostface Killer, and she has put herself back together thanks in part to her writing -- that is until she is visited by the knife-wielding maniac once again. Watch the trailer!

"Scream 4" opens in theaters April 15, 2011.
