Mona the Virgin Nymph (1970) (or simply Mona) was the second adult film, after Blue Movie released in 1969 by American artist Andy Warhol, depicting explicit sex to have received wide theatrical release in the United States. Mona, however, was the first such film with a plot. The minimal plot involved Mona (played by Fifi Watson), who had promised her mother that she would remain a virgin until her impending marriage.
Mona helped pave the way for films of explicit sex that later appeared in theaters—during the Golden Age of Porn—and was one of the films of the time on which some later films were based; indeed, Deep Throat borrowed elements of its plot two years later.
It was produced by Bill Osco and directed by Michael Benveniste and Howard Ziehm, though the film was screened without credits due to legal concerns. The earnings from this film helped finance the directors' later film Flesh Gordon. The team also produced another adult movie Harlot (1971), and Bill Osco later produced the similarly explicit Alice in Wonderland (1976).
