Though Three Dollar Bill Cinema is promoting its Innocence Lost retrospective series as four nights of “not-to-be-missed queer classics,” the titles should be viewed more for curiosity value than anything remotely legendary. On April 8, Cher endures a Mexican brothel in 1969’s Sonny Bono production Chastity (insert Chaz joke here). There’s a rare chance to view the 1958 remake of Mädchen in Uniform, starring the divine Romy Schneider as a lesbian schoolgirl (April 17). And some surprisingly frank (if silly) man-on-man action enlivens soft-core impresario Radley Metzger’s 1974 Score (April 22). (NR) STEVE WIECKING
