Heat Vision is reporting that Dimension's Scream 4 is rounding out its cast by adding Lake Bell and putting out offers to Ashley Greene, Hayden Panettiere and Rory Culkin for key starring roles.

Scream 4 reunites director Wes Craven with Kevin Williamson, who wrote the script for 1996's Scream. The story brings back original cast members Neve Campbell, David Arquette and Courteney Cox, though the new flick is seen as a passing of the baton to a new generation of slasher victims, with Williamson already under contract to write a fifth installment.

If deals are concluded, Greene would play Campbell's cousin Jill, essentially the heroine of the movie, and Panettiere would play her best friend, a nerdy film geek. Culkin would play a potential love interest for Jill.

Bell is negotiating to play a police officer who knew Sidney (Campbell) from high school.

Casting is proceeding slowly because Craven and Dimension are not sending the script to agencies in order to protect its secrecy. With only character descriptions, actors are having a difficult time deciding whether certain roles are for them. Reps for the actors declined comment.

The film will shoot in incentive-rich Michigan and planning a July start date.
