Potomac Theatre Company’s Swan Song: Annie

The Potomac Theatre Company’s 25th Silver Anniversary Season will also be its last.

“We’re going to have to close our doors,” said board member Carole Dell. “It’s really quite sad.”

The local theatre company will raise and lower its curtain for its final performances with its production of “Annie."

“It’s bittersweet because some of us have been working on this the entire time,” said Elie Pisarra Cain. “We’re all broken hearted, but we have to look at it realistically. …It's been a wonderful run."

Potomac Theatre Company's final production takes place this Friday and Saturday at 7:30 p.m. and on Sunday at 2:30 p.m. in the Blair Family Center for the Arts at the Bullis School, 10601 Falls Road. Call 301-299-8571. Visit www.potomactheatreco.org for more.
