This 1972 gross-out comedy by John Waters is now more than a generation old, and his brand of bad taste isn’t quite the cottage industry it once was. The plotline concerns a competition between Divine and the Marbles—a couple of up-and-coming sleazoids who peddle black-market babies to lesbian couples—for the title of “the World’s Filthiest Person.” With David Lochary, Mink Stole, and Edith Massey.
