In 1962, after just two matinees of "The Connection," the screenings were stopped, the theater closed, and the projectionist arrested, because the New York State Board of Regents had declared the film, about heroin addicts waiting for their dealer, to be obscene. Wendy Clarke, daughter of Shirley Clarke, the film's director, talks about the controversial film. She’s joined by Garry Goodrow, who played Ernie in it, and by Dennis Doros of Milestone Film & Video, which restored the film, "The Connection" opens May 4 at IFC Center.
