Add two more names to the list of potential victims to be killed by the psychotic Ghostface - stars Anna Paquin and Kristen Bell have signed on to make a cameo appearance in next year's Scream 4.

Director Wes Craven will once again helm the newest entry in the successful horror series, which is being penned by his Scream 1 & 2 screenwriter Kevin Williamson - Scream 3 writer Ehren Kruger is handling on-set revisions.

Neve Campbell returns as Sidney Prescott in Scream 4, which takes place in real-time, ten years after the events of the third installment.  Campbell will be joined by fellow Scream alumnus and real-life married couple David Arquette and Courteney Cox, who play onscreen married couple Sheriff Dewey Riley and Gale Weathers-Riley, respectively.

Several new actors are onboard to play potential victims of the new Ghostface killer (no Wu-Tang pun intended), including younger faces like Hayden Panettiere (Heroes), Emma Roberts, and Rory Culkin (Signs) - not to mentioned more experienced performers like Mary McDonnell.

[POTENTIAL SPOILERS AHEAD]

TV favorites Paquin (True Blood) and Bell (Veronica Mars) are both likely candidates to get off'd during the opening sequence of Scream 4.  The Scream franchise has made a tradition out of killing famous celebrities in the first five minutes of each film - one which began with Drew Barrymore in the original Scream (see below) - and it looks like the fourth entry will not buck that trend.

Scream 4 will reportedly be the first in a new trilogy - assuming it does well enough at the box office to justify two additional sequels.  While it is not an official reboot, the word is that Campbell and her fellow Scream veterans will "pass on the torch" to their younger costars in the fourth film.

The original Scream trilogy fashioned itself as a hip, post-modern horror flick in which characters were familiar with the clichés of the genre and paid the ultimate price when they forgot "the rules of survival."  How the fourth movie will update that premise for the new decade remains to be seen.

Scream 4 arrives in theaters in the U.S. on April 15th, 2011.
