 The first explicitly pornographic film with a plot that received a general theatrical release in the U.S. is generally considered to be "Mona the Virgin Nymph" (also known as "Mona"), a 59-minute 1970 feature by Bill Osco and Howard Ziehm, who went on to create the relatively high-budget hardcore/softcore (depending on the release) cult film "Flesh Gordon".The 1971 film "Boys in the Sand" represented a number of pornographic firsts.As the first generally available gay pornographic film, the film was the first to include on-screen credits for its cast and crew (albeit largely under pseudonyms), to parody the title of a mainstream film (in this case, "The Boys in the Band"), and to be reviewed by "The New York Times".
