Ruffalo, Murphy Team for Film

Actor Mark Ruffalo announced that he's been cast in the long-anticipated film adaptation of Larry Kramer's The Normal Heart, to be directed by Glee's Ryan Murphy, according to an interview with MTV.

"I just signed on tentatively with Ryan Murphy to do The Normal Heart, which is the Larry Kramer play," Ruffalo says. "It's really beautiful. Larry Kramer did a script adaptation. It's really powerful and strong and beautiful."

The Normal Heart, which was first performed in 1984 and is widely considered one of the most powerful plays of the past three decades, focuses on the AIDS epidemic in New York as seen through the eyes of protagonist Ned Weeks. Ruffalo, who will star as Weeks, can next be seen on-screen in Lisa Cholodenko's lesbian family dramedy The Kids Are All Right, opening in select theaters July 9.
