LOS ANGELES, CA - The entire cast of 'Scream 4' signed autographs and took photos with fans, except Kristen Bell - who seldom engages with fans when she is with boyfriend Dax Shepard. Anthony Anderson arrived first, followed by David Arquette. Alison Brie and Emma Roberts were next. Hayden Panettiere was on her way to the fans, as Emma Roberts was returning to the premiere and Hayden lifted Emma up when their paths crossed in the crosswalk. Adam Brody crossed to sign and was greeted with shrieks from the chicks in the crowd. Neve Campbell and Courtney Cox closed out the premiere with a bang. After party coverage includes True Blood's Anna Paquin, Nico Tortorella, Matthew Lillard, Shenae Grimes, and Marilyn Manson with Eli Roth leaving the party and trying to drive away with paparazzi trailing them.
