R. P. M.

R. P. M. is a 1970 American drama film directed by Stanley Kramer, starring Anthony Quinn and Ann-Margret. As the film's poster notes, the title is an initialism for "revolutions per minute", which at the time was a common term for the variable speed of a record player's turntable and generally a unit of rotational speed for rotating machines. It is a reference to students' smoke-filled drinking parties and how in the 1960s students evolved politically so quickly that they went through many political revolutions in little time.
