A Dirty Shame is a 2004 American satirical sex comedy film written and directed by John Waters and starring Tracey Ullman, Johnny Knoxville, Selma Blair, and Chris Isaak. A Dirty Shame is currently the last film directed by Waters, who said that the film's poor box office performance had prevented him from making more films. Plot The people of Harford Road are firmly divided into two camps: the neuters, the puritanical residents who despise anything even remotely carnal; and the perverts, a group of sex addicts whose unique fetishes have all been brought to the fore by accidental concussions. Repressed Sylvia Stickles finds herself firmly entrenched in the former camp. One day, after leaving her promiscuous daughter Caprice (nicknamed Ursula Udders because of gargantuan breasts and a penchant for indecent exposure while dancing at a local dive bar) locked up over the garage, under house arrest "for her own good", Sylvia is smacked on the head by a passing car and meets Ray-Ray Perkins, a local mechanic and self-styled "sex saint" who opens her mind to a whole new world of sensual pleasure, as he and his followers search for the ultimate sex act. Eventually, through a series of bizarre head knockings, everyone in the Harford Road area of Baltimore becomes a sex addict, as Ray-Ray shoots semen out of his head and becomes the messiah of "Let's Go Sexin'!" Cast Production John Waters decided to make the film after discovering several sexual slang terms and branches existed on the internet, explaining the groups and terminology found in the film. The film was shot entirely on-location in Baltimore on Harford Road which is prominently featured in the film. In a featurette on the DVD veteran stage actress Suzanne Shepherd recalled that when she was cast as Big Ethel, she was completely unfamiliar with Waters' work and she had no idea what to expect when she showed up for the first script review. Horrified by what she was reading, she became so distraught that she began to cry. She tried to quit the project but Waters and her cast mates managed to persuade her to stay. Paul Giamatti was originally slated to play Vaughn Stickles, but dropped out before filming began. The film received an NC-17 rating from the Motion Picture Association of America (MPAA). Many major theater chains will not screen a film with that rating, and many media outlets
