Matt Bomer, Jim Parsons Join All Star Cast

Actors Matt Bomer, Jim Parsons, Alec Baldwin, and Julia Roberts are set to join previously announced Mark Ruffalo in Ryan Murphy's film adaptation of Larry Kramer's landmark play The Normal Heart, according to The Hollywood Reporter.

Originally produced in 1985, Kramer's searing drama about the AIDS epidemic in New York received an acclaimed, Tony Award-winning revival last year. Murphy optioned the rights in August and cast Ruffalo as the Kramer stand-in Ned Weeks. The Reporter reveals that Roberts will portray Dr. Emma Bookner, a role that won a Tony Award for Ellen Barkin, while Alec Baldwin has been cast as Weeks's brother.

Bomer, who in March will also appear in the staged reading of 8, Dustin Lance Black's marriage equality play, will costar as Week's boyfriend Felix Turner, a role which garnered a Tony Award for John Benjamin Hickey. Parsons will recreate his role in last summer's production as a Southern-born gay activist.

Murphy will direct the script adapted by Kramer.
