Dimension Films has officially released an extended trailer for the upcoming Wes Craven sequel Scream 4. The footage sets up some of the new rules the film will parody and introduces new faces such as babes Emma Roberts, Kristen Bell, Hayden Panettiere and her horrible bull-dyke haircut and “True Blood’s” Anna Paquin.

Also seen in the trailer are old-schoolers Neve Campbell, Courteney Cox, and David Araquette, who return to the mix in their respective roles as Sidney Prescott, Gale Weathers-Riley, and Sheriff Dewey Riley. The film is the beginning of a new trilogy and is written by franchise creator Kevin Williamson (“The Vampire Diaries”).

Scream 4 will be in theaters on April 15, 2011.
