'Scream 4' drafts new scribe for rewrites; Hayden Panetierre not pleased with 'dumbed down' role [UPDATED]

hayden-panettiere-getty.jpgAll is not well in Woodsboro. As we previously reported, significant script changes have created some tension on the set of "Scream 4."

Lauren Graham's role was so reduced that she dropped out of the project, sources close to the production tell Zap2it. [UPDATE: According to The Wrap, Graham's publicist says she dropped out of the film due to "scheduling conflicts."] Now it appears that Hayden Panetierre's part has changed as well... and who's at fault may surprise you.

Zap2it has also learned that the slasher flick's script is now in the hands of Ehren Kruger, not the creator of the franchise, Kevin Williamson.

In fact, word is that Williamson's involvement with the project has come to an end entirely -- meaning "Scream 5" is a no-go at this time.

Kruger's writing resume includes "Transformers: Revenge of the Fallen" and "The Ring," and more significantly, "Scream 3." While the first two "Scream" movies, penned by Williamson, were adored by fans and critics alike, "Scream 3" was... well, not.
