The Immoral Mr. Teas (1959) is the first commercially successful film of director Russ Meyer. The film was described as a nudist comedy and was noted for exhibiting extensive female nudity. The film cost $24,000 to produce and eventually grossed more than $1,500,000 on the independent/exploitation circuit.
The Immoral Mr. Teas was the first American "above ground" movie since the pre-Code early sound era to show female nudity without the pretext of naturism. It is considered to be the first commercially viable American "skin flick" and popularized the nudie cutie genre.
The movie consists of a series of short scenes. In a sense, no one is actually naked; the only nudity seen is through the viewpoint and vivid imagination of Mr. Teas. Mr. Teas' mental constructions extend beyond the nudity (always exclusively of female characters)-there is an underlying surrealism in Mr. Teas' imagination that results in a number of genuinely bizarre situations.
