On a less classical note is Seijun Suzuki's Gate of Flesh (1964; Oct. 29), which reimagines occupied Tokyo as a trash heap of whores, beggars, and horny American GIs. Garish images of a quartet of prostitutes ritually assaulting each other for the one unforgivable sin -- screwing for free -- must have startled audiences of the time, but by the next decade Norifumi Suzuki's School of the Holy Beasts (1974; Oct. 1) pulled us over the edge. In this feast for S/M lesbian nun aficionados, the Brides of Christ in the ill-named Sacred Heart Convent have little time for their devotions; they're too busy brawling, getting laid, and of course pushing each other into an acid bath conveniently hidden under a trap door. The series begins at 8 p.m. Friday at Yerba Buena Center for the Arts, 701 Mission (at Third Street), S.F. Admission is $3-6; call 978-ARTS.
