What 1972 movie revolves around the happenings at the Kit-Kat Klub?

"Cabaret" is a 1972 American musical drama film which was directed by Bob Fosse and which starred Liza Minnelli, Michael York, and Joel Grey. In 1931 Berlin, young American Sally Bowles (Liza Minnelli) performs at the Kit Kat Klub. A new British arrival in the city, Brian Roberts (Michael York), moves into the boarding house where Sally lives. A reserved academic and writer, Brian gives English lessons to earn a living while completing his doctorate. Sally tries seducing Brian and suspects he may be gay. Brian tells Sally that on three previous occasions he has tried to have physical relationships with women, all of which failed. They become friends, and Brian witnesses Sally's anarchic, bohemian life in the last days of the German Weimar Republic. Sally and Brian become lovers despite their earlier reservations; they conclude that his previous failures with women were because they were "the wrong three girls".

Director Bob Fosse decided to increase the focus on the Kit Kat Klub, where Sally performs, as a metaphor for the decadence of Germany in the 1930's by eliminating all but one of the musical numbers performed outside the club. Every song except "Tomorrow Belongs to Me" is executed in the context of a Kit Kat Klub performance.

The film was immediately successful at the box office. By May 1973 it had earned rentals of $4.5 million in North America and $3.5 million in other countries and reported a profit of $2,452,000.
