BRUNSWICK — The Theater Project’s holiday show, “Miracles on School Street,” on Dec. 9-18 will feature all age groups that gather at the 14 School St. site.

Founded in 1971, The Theater Project has resided in that theater since 1986.

A class of third, fourth and fifth-graders will present “The Penguin Who Saved Christmas,” directed by Lee K. Paige, which tells the tale of Penelope, a lonely penguin who is called upon to save Christmas.

“The Elf Rebellion,” performed by sixth-, seventh- and eighth-graders and directed by Elise DeRosa, is the story of a near shutdown in Santa’s workshop. Fortunately for children worldwide, Santa and Mrs. Claus are quicker of wit than the elves, and Santa’s workshop continues.

The Theater Project’s Young Company will present a new take on Handel’s “Hallelujah Chorus” in this year’s holiday show. “I decided it was time we took on something classical during the holidays,” director Al Miller said. “This remarkable chorus of high-school actors is up to the task, thanks to a lot of hard work.” In addition, the Young Company will provide a visual treat in its sometimes tuneful version of “The Twelve Days of Christmas.”

A cast made up of actors from the community, the Theater Project’s Professional Ensemble and Center Stage Players will stage an adaptation of John Cheever’s short story, “Christmas Is a Sad Season for the Poor.” Adapted by Al Miller, Cheever’s touching and humorous story focuses on Charlie, the elevator operator in a New York apartment building in the 1940s. Charlie decides Christmas is not a happy time until well-to-do apartment dwellers change his mind.

Miller is likely to tell a story and Don Weatherbee, Company actor and a directing member of The Theater Project’s collaboration with Spindleworks, will present two short holiday dance pieces.

Jim Hall, the theater’s sound designer and composer who also acts with the Company, and singer-songwriter Lauryn Hottinger will add music to the holiday production, including an audience participation piece.

“Miracles on School Street” will be staged at 7:30 p.m. on Friday and Saturday, and at 2 p.m. on Sunday. Tickets are pay what you want. For tickets, call 729-8584 or visit www.theaterproject.com.
