Cult filmmaker John Waters has called the new documentary That’s Sexploitation a “wall-to-wall lazy Susan of tits, ass and hilarity.” It’s a pretty apt description of horror filmmaker Frank Henenlotter’s flick that provides an overview of the underground “adults only” cinema that existed from 1930 to 1970. There’s lots of nudity in the movie so be sure to leave the kids at home for this one. It makes its Cleveland theatrical premiere tonight at 9:05 at the Cleveland Institute of Art Cinematheque. Tickets are $9. (Niesel)
