Produced by Ryan Murphy, The Boys In the Band had its first preview on Broadway last night and will have it’s official opening on May 31.

Mart Crowley’s groundbreaking play, first performed in 1968, is centered around a group of gay men in 1960s Manhattan all getting together to celebrate the birthday of their friend Harold. As the plot develops and the party continues, old wounds from each of the characters’ past are resurfaced, forcing each individual to deal with their personal demons.

The Boys In The Band was made into a film in 1970, sparking the first ever gay protests outside cinemas by groups who were outraged by what was then seen as a negative representation.

Quinto, Bomer and Parsons will be joined on stage by gay Broadway stars Robin De Jesús, Brian Hutchison, Tuc Watkins and Charlie Carver.

In this behind the scenes video, Quinto says: “We’re responsible for standing up and being acknowledged, and celebrating ourselves, and celebrating our community in a way that shows these people who are trying to undo the progress that we have made, that we’re not going anywhere.”

What I like so much about The Boys In The Band is how the play right now reads so much as ‘look at how things have changed and look at how they haven’t’,” adds Parsons.
