Dialogue, special effects, and hordes of creatures and characters from the “Lord of the Rings” movie trilogy come to life when Charles Ross throws himself around the stage in this solo show. He can be everything from the monstrous orcs (played with many grunts) to the hobbit Sam (wide eyes) and greedy Gollum (hunched over on the floor). And he doesn’t describe battles–he becomes them. Unlike his One-Man Star Wars Trilogy, this hour-long encapsulation of the films requires more than a passing familiarity with them. It’s easy to get lost amid all the characters and plot lines. Still, Ross’s energy and quick-change artistry are winning. Particularly charming are his sly characterizations and witty asides; we know he’s the elf Legolas, for example, when he starts combing–and eventually blow-drying–his (imaginary) long, beautiful hair.Through 2/14: Sat 10:30 PM, Mon 7 PM.
