Glee creator Ryan Murphy and Mark Ruffalo – star of the gay parenting flick The Kids Are Alright – will team up in the upcoming big screen adaption of the AIDS drama The Normal Heart.

The movie is based on the semi-autobiographical Larry Kramer play by the same name. The play's 1985 premiere was critically acclaimed. Kramer has signed on to write the screenplay.

“I just signed on tentatively with Ryan Murphy to do The Normal Heart, which is the Larry Kramer play,” Ruffalo told MTV News. “It's really powerful and strong and beautiful.”

Ruffalo will play the lead character of Ned Weeks, a gay writer-AIDS activist who founds an advocacy group in New York City during the early years of the AIDS pandemic. Ned's confrontational style thrusts the unprepared group into the media spotlight.

“It's a juicy part,” the 42-year-old actor added. “It's just a great role, man. He's a fighter, you know?”

Murphy's capacity in the project has not been announced.
