HBO announced Thursday that it will debut the film adaptation of The Normal Heart, Larry Kramer's Tony-winning AIDS play, in May.

The film's all-star cast includes Mark Ruffalo, Matt Bomer, Taylor Kitsch, Jim Parsons and Julia Roberts.

Ryan Murphy (Glee, Eat Pray Love) directed the feature length film, which is based on a script written by Larry Kramer (Women in Love).

Murphy said Thursday during a Television Critics Association panel that it was “sort of thrilling” to feature Bomer (White Collar) and Parsons (Big Bang Theory), both of whom are openly gay, as leading men in an AIDS TV drama.

Ruffalo – a co-star of the 2010 lesbian moms flick The Kids Are Alright – will tackle his first gay role playing Ned Weeks, the hero of Kramer's play about the early days of the AIDS pandemic in New York City.
