Not a lot of explaining is necessary here. This transsexual, sci-fi musical from 1975 is the essential cult film. To accompany the lusty gyrations and tuneful dialogue of Tim Curry, Susan Sarandon, Barry Bostwick, et al., there will be a special "shadowcast"--with costumes, props, the whole shebang--performing live on stage in front of the film. As always audience participation is not just encouraged but mandatory. For the fifth year in a row, presented by Pride & Equality magazine. 100 minutes R.
