Born December 27, 1962 in Rockford, Illinois, US as Joseph Mantello, he is an American actor, director, and producer, best known for his work in Broadway theatre. His mother Judy was of half Italian descent and his father Richard Mantello, an accountant, was of Italian descent. He graduated the North Carolina School of the Arts and in 1984 moved to New York City. His first acting roles were in the plays "Walking the Dead" and "The Baltimore Waltz" and in 1993 he played Louis in the original Broadway production of Tony Kushner's "Angels in America". The production won both Tony and Drama Desk awards, and Mantello himself was nominated for both as well. He later switched from acting to directing, winning the Tony Award for Best Direction of a Play in 2003 for Richard Greenberg's "Take Me Out" and the Tony Award for Best Direction of a Musical a year later for Stephen Sondheim's "Assassins". He directs a wide variety of shows on Broadway, his directing credits include the hit musical "Wicked" and the play "The Boys in the Band", which was later made into the movie The Boys in the Band (2020). He also returns to acting from time to time, both on Broadway (as Ned in Larry Kramer's "The Normal Heart" and as Tom in Tennessee Williams's "The Glass Menagerie") and in television (in a smaller role of Mickey in The Normal Heart (2014) and as Dick Samuels in Hollywood (2020), both directed by Mantello's friend Ryan Murphy). In 2018 he was inducted into the American Theater Hall of Fame. He lives in New York City with his partner Paul Marlow.
