The Immoral Mr. Teas is the first commercially successful film of director Russ Meyer, released in 1959.

Teas is a clumsy and shy man, who likes to watch happy couples, and who daydreams when looking down the necklines of women he meets.

After undergoing surgery at the dentist, Teas realizes that the anesthetic has overcome his inhibitions, and given him x-ray vision, enabling him to see all women without their clothes.

Before this film was released, the only moving pictures exhibiting extensive nudity were either underground (covertly produced and distributed) pornographic films, typically distributed "under the counter" in 16 mm black and white movies, or naturist pictures, openly displayed in specialized movie theaters, usually under the cover of exhibiting the fun and freedom of nudism in naturist reserves.

Meyer agreed provided he could do something with a scriptline and that he could use "well built girls instead of the usual unattractive types that populated nudist films.

There's a lot of stuff on the girl next door, the common man, the voyeur - little nude photo essays.

"[6] 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.

"[3] According to The Wall Street Journal, the film led to over a hundred imitations being made in the next 12 months.
