Cabaret is a 1972 American musical period drama film directed by Bob Fosse and written for the screen by Jay Presson Allen. It stars Liza Minnelli, Michael York, Helmut Griem, Marisa Berenson, Fritz Wepper and Joel Grey. Set in Berlin during the Weimar Republic in 1931, under the presence of the growing Nazi Party, the film is an adaptation of the 1966 Broadway musical Cabaret by Kander and Ebb, which was based on Christopher Isherwood's semi-autobiographical novel The Berlin Stories (1945) as well as John Van Druten's 1951 play I Am a Camera, which was itself adapted from Isherwood's novel. Multiple numbers from the stage score were used for the film, which also featured three other songs by Kander and Ebb, including two written for the adaptation.
In 1931 Berlin, a young, openly promiscuous American Sally Bowles performs at the Kit Kat Klub. A new British arrival in the city, Brian Roberts, moves into the boarding house where Sally lives. A reserved academic and writer, Brian must give English lessons to earn a living while completing his doctorate. Sally tries to seduce Brian, but he tells her that on three previous occasions he has tried to have sexual relationships with women, all of which failed. They become friends, and Brian witnesses Sally's bohemian life in the last days of the Weimar Republic. When Brian consoles Sally after her father cancels his meeting with her, they become lovers, concluding that his previous failures with women were because they were "the wrong three girls".
