While the Saco River Theatre in Bar Mills was built in 1897 as a Universalist chapel, it found new life as a silent movie house, Maine State Grange hall, and even a venue for lively auctions. For the past 24 years it has been the area’s cultural arts center, hosting concerts, theatrical productions, silent movies, and contra dances. Its resident acting company, The Originals, opened a new season April 25 with a production of “Marvin’s Room,” supported by the Maine Theater Fund. The fund also has provided grants for productions this season by the Freeport Community Players, Midcoast Actors’ Studio, and New Surry Repertory Theatre and Acting School.
