'Nightmare' beginning for trio of actors

Kellen Lutz, Thomas Dekker, Rooney Mara join horror pic

Like lambs to the slaughter, "Twilight" actor Kellan Lutz, "Terminator" TV show star Thomas Dekker and Rooney Mara have joined the cast of New Line's re-imagined "A Nightmare on Elm Street," being directed by Samuel Bayer and produced by Platinum Dunes.

Lutz, who is in negotiations, would play a popular school jock.

Dekker is an alpha male trying to get back together with his girlfriend. Mara plays a girl who can't wait to leave town after graduation.

Those young dreams will prove to be dust as the duo join Kyle Gallner, in the role played by Johnny Depp in the 1984 pic, as fodder for slasher Freddy Krueger, being played by Jackie Early Haley.

"Nightmare" is slated to begin shooting May 5 in Chicago.

Lutz played Emmett Cullen in "Twilight," a role he is reprising for the sequel, "New Moon," which is shooting in Vancouver. His part in "Nightmare" would not be scheduled until later in the shoot. The actor, repped by Innovative, also appeared in "90120" and "Generation Kill."

Dekker, repped by ICM and the Schiff Co., is coming off starring on Fox's "Terminator: The Sarah Connor Chronicles." He next appears on the big screen in New Line's "My Sister's Keeper" with Cameron Diaz and Abigail Breslin.

Gersh-repped Mara, the sister of Kate Mara, has "The Winning Season" with Sam Rockwell and "Youth in Revolt" with Michael Cera coming out this year.
