When a beloved community theater is about to turn 50, it is time to celebrate in a big way. For the next three years, Theatre Three in Port Jefferson will present a series of special events building up to its 50th anniversary, beginning with Life in the Theatre: A Glimpse Behind the Curtain on Sunday, May 20, at 7 p.m.

The fundraiser, which will be hosted by actor, comedian, broadcaster and Theatre Three alum John Fugelsang, will include an original comedy by Executive Artistic Director Jeffrey Sanzel followed by a special guest appearance by musician, actor, writer and radio host Seth Rudetsky.

Founded in 1969 by Jerry Friedman and John and Linda Herr, the troupe started out performing at the Smith Haven Ministries at the Smith Haven Mall. “They all lived in the Three Village area, hence the name, ‘Theatre Three,'” said board member and former artistic director Bradlee Bing, who joined the group shortly after.

Over the years, Theatre Three occupied several different spaces including in the First Presbyterian Church on Main Street in the village before purchasing the current building at 412 Main St. in 1979 after the United Artist Theater closed. In the beginning, there were “only adult-themed musicals, plays and cabaret-style revues,” Bing said. The theater has since expanded to offer children’s theater, educational tours, concerts and acting lessons.

“It is inconceivable that 48 years have passed so quickly,” said Bing who first approached Sanzel about launching a three-year celebration.

The event on May 20 will open with the world premiere of “Life, the Theatre, and Other Unlikelihoods,” a one-act musical  featuring original songs by Brian Crawley (Tony nominee for “Violet”), Tim Peierls, Douglas J. Quattrock and Sanzel. Starring Dylan Robert Poulos, the play will celebrate the joys and challenges of becoming an actor, from taking acting lessons as a child to landing that big role, or not.

Directed and narrated by Sanzel, the 17-member cast, playing dozens of roles, will also include Melanie Acampora, Marci Bing, Meg Bush, TracyLynn Conner, Jessica Contino, Ginger Dalton, Sari Feldman, Andrew Gasparini, Eric J. Hughes, Linda May, Phyllis March, Steve McCoy, Cameron Turner, Steven Uihlein and Stephen Wangner.

For Sanzel the experience of creating this one-act musical has morphed into “becoming a celebration of what we do … and is one of the greatest and most joyous writing experiences I’ve ever had.”

He continued, “Yes, the world of theater is fun and interesting but it is a huge amount of work and an enormous commitment. The flipside is the reward which is extraordinary. This play traces how we all come together as family in this amount of time and then we say goodbye and the poignancy of that.”

For Bing, this event is just the beginning. “We have identified it as year one, getting ready, year two, getting set and year three, go. We are developing activities that will prepare us for our final year celebration that will be a three-day event featuring a cocktail reception free of charge open to everyone that has ever been associated with the theater: actor, musician, technician, subscriber, ushers, family and friends on June 5, a semiformal sit down recognition, celebrity dinner on June 6 and a show at the theater highlighting 50 years of theater performances on June 7.”

For Sanzel, “It really is a celebration of theater, the universality, but it is also a celebration of Theatre Three. This event is the perfect launch toward our 50th anniversary.”

Theatre Three, 412 Main St., Port Jefferson will present “Life in the Theatre” on May 20 at 7 p.m. Tickets are $50 presale, $75 at the door. Proceeds will go toward programming at the theater. To order, please call 631-928-9100 or visit www.theatrethree.com.
