This gripping and well-acted theatrical duet (1993) evokes a kinder, gentler Oleanna; the setting is the apartment of a paralegal assistant (Karen Sillas) and the circumstance is her first date with a coworker (writer-director Tom Noonan). Neither character is quite who she or he appears to be, and a subtly modulated power shift between the two gradually takes place as each unveils an inner self. The film won a screenwriting award at Sundance, and the actors both seem to know what they’re doing every step of the way. Music Box, Friday through Tuesday, December 16 through 20.
