This four-day retrospective spotlighting Rosa von Praunheim, a stalwart figure in gay cinema, peaks with a red-letter performance of his life, I'm a Tomato — a fitting title, given how much catch-up there is (ha-cha!). For 40 years now, the full-tilt activist ("Rosa" stands for the pink that branded concentration-camp homosexuals, "Praunheim" for a Frankfurt district) has been a provocative, prolific chronicler of AIDS, transsexuals, cannibals, and his repressed brethren. Beside the seminal call-out of gay Uncle Toms, It Is Not the Homosexual Who Is Perverse, But the Society in Which He Lives, the enlightened program also shines on America's gay-liberation movement and women under duress, such as transvestite Charlotte von Mahlsdorf, who endured Nazis, neo-Nazis, and everything in between.
