England doesn’t swing and love doesn’t conquer all in Polish expatriate director Jerzy Skolimowski’s Deep End, one of the ’70s’ great lost cinematic treasures. (It’s rarely screened and not available on video.) Set in a run-down London bathhouse, this rueful comedy from the co-scripter of Knife in the Water is the vividly color-coordinated tale of an oversensitive teenager’s unrequited passion for his beautiful, slightly older co-worker (played by former Paul McCartney squeeze Jane Asher). Neo-hipsters who have just discovered Krautrock should note that the 1970 flick features a soundtrack by Can. The film will be shown with an episode of The Bob Newhart Show that also addresses the subject of obsessive love. At 7 p.m. at the Mary Pickford Theater, Madison Building, Library of Congress, 1st St. & Pennsylvania Ave. SE. Free, but reservations required. (202) 707-5677. (MJ)
