"The story of a city in denial," The Normal Heart, according to press notes, "unfolds like a real-life political thriller -- as a tight-knit group of friends refuses to let doctors, politicians and the press bury the truth of an unspoken epidemic behind a wall of silence. First produced by Joseph Papp at New York’s Public Theater, the play was a critical sensation and a seminal moment in theater history. So ahead of its time was this play that many of the core issues it addresses – including gay marriage, the healthcare system and, of course, AIDS – are just as relevant today as they were when it first premiered." The Normal Heart will support a group of dedicated nonprofit organizations, including The Actors Fund and Friends In Deed, among others.

Producers are Daryl Roth, Paul Boskind and Martian Entertainment in association with Gregory Rae and Jayne Baron Sherman/Alexander Fraser.
