Hayden Panettiere attended the "Scream 4" Los Angeles premiere yesterday in a crimson cocktail dress. Although her co-stars looked good, Hayden stood out in the crowd in her vibrant red dress.

In the fourth film, Sidney Prescott (Neve Campbell) comes face to face with her greatest fear after returning home to Woodsboro and getting caught in the center of another bloodbath. Courteney Cox, David Arquettte, Panettiere, and Emma Roberts also star.

Horror movie maestro Wes Craven tormented Hayden and Emma on set of "Scream 4" with a series of spooky pranks. Waven told a crew member to don the eerie Ghostface mask and jump out on the actresses throughout filming.
