Christopher Munch’s brilliant and concise account of what might have happened during John Lennon and Brian Epstein’s four days on vacation in Barcelona in 1963–written, directed, produced, and shot by Munch (who also photographed The Living End) on location in black-and-white 35-millimeter. Visually spare and running for only an hour, this benefits not only from one terrific performance (David Angus as Epstein) and a pretty good one (Ian Hart as Lennon), but also from a filmmaking confidence and lack of pretension that makes every passing nuance register keenly. On the same program, Stephen Cummins and Simon Hunt’s Australian short Resonance (1990), about gay bashing in Sydney. (Music Box, Friday through Thursday, January 8 through 14)
