7. A Clockwork Orange (1971)
Director: Stanley Kubrick
Stanley Kubrick's take on a dystopian British society—based on Anthony Burgess' novel—was released in 1971 but didn't stay in theaters for long. It was released with an X rating in the U.S., quickly condemned by the Catholic Church and withdrawn from British theaters by Kubrick himself after a series of crimes were linked to the brutality in the film. In one case, as in the GIF above, a woman was raped by a group of men who sang "Singin' in the Rain" throughout.
