Though “Normal Heart” isn’t slated to premiere on HBO until May, a sequel to the Ryan Murphy-helmed film is already in the works at the pay cabler, Variety has confirmed.

As first reported by Deadline, HBO has commissioned a script by “Normal Heart” scribe Larry Kramer for a potential sequel. Project would be directed by Murphy, and possibly see the return of “Normal Heart” leads Mark Ruffalo, Julia Roberts and Jim Parsons.

Kramer penned “Normal Heart” as a play, and debuted the off-Broadway production in 1985. “Normal Heart” focuses on the 1980s AIDS crisis in New York. Murphy announced in 2011 that he optioned the play, and aggressively pursued Roberts to star in the drama. HBO has yet to set a specific premiere date for “Normal Heart.”
