Heat Vision is reporting that Adam Brody, Marley Shelton and Erik Knudsen have joined the cast of Scream 4, while Ghouls on Film says that Lauren Graham has exited the sequel due to date conflicts and script changes.
Wes Craven has started directing in Michigan from a Kevin Williamson script. The Dimension Films release stars Neve Campbell, Courteney Cox Arquette, David Arquette, Emma Roberts, Hayden Panettiere, Rory Culkin, Nico Tortorella, Anthony Anderson and Marielle Jaffe.
Brody will play a cop recently graduated from college who was raised on the "CSI" TV series.
Shelton will play a deputy who knew Campbell's character in high school. Lake Bell had been in negotiations for the role.
Knudsen will have a role similar to the one played by Jamie Kennedy in the first two installments, a character who is familiar with horror movie conventions and a provider of comic relief.
