The play, created by members of the Plastic Theatre and conceived and directed by Tony Speciale, will now continue to July 31. Producers have been circling the show to gauge its viability for a possible future life.

"We are deeply moved by how this story which had been kept silent for 80 years has struck such a responsive chord with audiences, giving voice to a community of young men who were ahead of their time and would have otherwise been forgotten," said CSC artistic director Brian Kulick, in a statement.

Jessica R. Jenen, executive director of CSC, said in a statement, "We are seeing an extraordinary number of audience members attending multiple times, bringing friends and colleagues. We're thrilled that we can continue to run this timely and powerful play for one final week at CSC, and look forward to its future life elsewhere."

According to CSC, Unnatural Acts "is inspired by events that occurred at Harvard University in the spring of 1920, when a student's suicide sparked a campus-wide investigation by a panel of administrators who convened to investigate, expose and ultimately expel a group of homosexual students. Both intimate and epic, Unnatural Acts explores themes of fear and societal intolerance that are as relevant today as they were 91 years ago."

The cast features Jess Burkle, Joe Curnutte, Frank De Julio, Roe Hartrampf, Roderick Hill, Max Jenkins, Brad Koed, Jerry Marsini, Devin Norik, Will Rogers and Nick Westrate. Unnatural Acts performs Tuesdays through Fridays at 8 PM; Saturdays at 2 PM and 8 PM and Sundays at 2 PM. Tickets are $60 for weekday performances and $65 for weekends.
