"Scream 4" has cast a young star to play one of the major characters. Entertainment Weekly reports that Emma Roberts has signed on to portray Jill, one of the film's primary heroines. Her role is said to be similar to the one belongs to Neve Campbell in the previous "Scream" flicks.

"I'm so excited to be part of this ground-breaking franchise. It's the perfect opportunity for me to do something completely different than I've ever done before," Roberts says on her involvement in the upcoming project. Director Wes Craven adds, "Emma's talent, beauty, and range will add immensely to the sophistication, intensity, and fun of the 'Scream' franchise as it returns to the screen once more."

Robert's casting consequently ends Ashley Greene's chance to join the fourth installment of the thriller film franchise. The "Twilight" thesp was earlier reported to be a lead actress in the film, but Weinstein Company announces that the role intended for Greene is the one taken by Roberts.

The "Heroes" beauty is said to play Jill's nerdy film geek best friend, the "It's Complicated" star is in talks to portray a police officer who knew Sidney from high school, while the brother of Macaulay Culkin would play a potential love interest for Jill. However, the studio has not confirmed their involvement.

Neve Campbell, Courteney Cox as well as David Arquette are set to reprise their roles as Sidney Prescott, Gale and Dewey respectively in the upcoming film. Shooting is scheduled to start in Michigan this July for April 15, 2011 U.S. release date.
