The final project conceived by the late screenwriter Dennis Potter (Pennies From Heaven, Track 29), Midnight Movie reportedly features such characteristic features as a film-within-a-film, sequences that contrast memory and actuality, and acid humor. The film, directed by Renny Rye, screens at 8 p.m. at the Hirshhorn Museum & Sculpture Garden’s Ring Auditorium, 8th & Independence Ave. SW. FREE. (202) 257-2700. (Mark Jenkins)
