Never on Sunday (also known as Pote Tin Kyriaki (Ποτέ Την Κυριακή)) is a 1960 black-and-white film which tells the story of Ilya, a prostitute who lives in the port of Piraeus in Greece, and Homer, an American tourist — a classical scholar enamored with all things Greek. Ilya is a character close to the "hooker with a heart of gold" cliche. Homer feels Ilya's life style typifies the degradation of Greek classical culture and attempts to steer her onto the path of morality (still another kind of the Pygmalion story). The film stars Melina Mercouri and Jules Dassin.

The film gently submerges the viewer into Greek culture, including dance, music, and language (through the use of subtitles).

The signature song and the bouzouki theme of the movie became hits of 1960s and brought Manos Hadjidakis, the composer, an Academy Award.

The movie was written and directed by Dassin.

It won the Academy Award for Best Song (Manos Hadjidakis for Never on Sunday). It was nominated for the Acdemy Awards for, respectively, Best Actress in a Leading Role (Melina Mercouri), Best Costume Design, Black-and-White, Best Director and Best Writing, Story and Screenplay - Written Directly for the Screen.
