Two new blondes have been added to the cast list for Scream 4. And in the grand tradition of established actresses (often blondes – ahem –  Drew Barrymore and Sarah Michelle Gellar) having tiny cameo roles, Anna Paquin and Kristen Bell will probably both be killed off horrifically. The casting news was reported by USA Today, today!

The Scream 4 cast now includes: Neve Campbell, David Arquette and Courtney Cox Arquette, Emma Roberts, Hayden Panettiere, Lake Bell (or did she pull out?), Adam Brody, Allison Brie and Mary McDonnell.

If they are still making a movie-within-a-movie inside of Scream 4, as they did with the Stab franchise – perhaps one of them will be the new Sidney Prescott in the movie? In Scream 2, Sidney was played by Tori Spelling. I could see them using Paquin’s True Blood fame to have cast her and making a joke about how she’s a new scream queen. (And let’s not forget that Heather Graham played the role of Casey Becker in the movie Stab in Scream 2.)

What’ll be fun for Kristen Bell is that she’s really good friends with (her now co-star) Hayden Panettiere in real life (yes, even before both being on Heroes.) Hopefully they’ll get a scene together, or at least we’ll get some pretty pictures of them together at the Scream 4 premiere.

Do you have a theory about Scream 4 and these actresses’ parts in it? Share it in the comments!
