Jonathan Groff

Glee actor Jonathan Groff has signed on for a dramatic role in Ryan Murphy’s upcoming HBO film The Normal Heart.

The film is based on a largely autobiographical play by Larry Kramer chronicling the rise of the HIV-AIDS crisis in New York City in the early 1980s. Groff will play Craig, an early victim of the disease and the first lover of Bruce Niles (Friday Night Light‘s alum Taylor Kitsch), an investment banker who becomes an AIDS activist.

Also just cast: Broadway actor and director Joe Mantello as Mickey Marcus, a man who’s an instrumental member of the Gay Men’s Health Crisis.

The actors join previously announced cast members such as Julia Roberts (Dr. Emma Brookner), Mark Ruffalo (Ned Weeks), Matt Bomer (Felix Turner) and Jim Parsons (Tommy Boatwright). The Normal Heart is expected to premiere next year.
