Cabaret is a 1972 American musical drama film which was directed by Bob Fosse and which starred Liza Minnelli, Michael York, and Joel Grey. Situated in Berlin during the Weimar Republic in 1931, under the presence of the growing Nazi Party, the film is loosely based on the 1966 Broadway musical Cabaret by Kander and Ebb, which was adapted from the novel The Berlin Stories / Goodbye to Berlin (1939) by Christopher Isherwood and the 1951 play I Am a Camera adapted from the same book. Only a few numbers from the stage score were used for the film; Kander and Ebb wrote new ones to replace those that were discarded. In the traditional manner of musical theater, called an "integrated musical", every significant character in the stage version sings to express his or her own emotion and to advance the plot.

Roger Ebert gave a positive review, saying: "This is no ordinary musical. Part of its success comes because it doesn't fall for the old cliche that musicals have to make you happy. Instead of cheapening the movie version by lightening its load of despair, director Bob Fosse has gone right to the bleak heart of the material and stayed there well enough to win an Academy Award for Best Director." Variety says: "The film version of the 1966 John Kander-Fred Ebb Broadway musical Cabaret is most unusual: it is literate, bawdy, sophisticated, sensual, cynical, heart-warming, and disturbingly thought-provoking. Liza Minnelli heads a strong cast. Bob Fosse's generally excellent direction recreates the milieu of Germany some 40 years ago." Jamie Russel from BBC.com reviewed: "The first musical ever to be given an X certificate, Bob Fosse's 'Cabaret' launched Liza Minnelli into Hollywood superstardom and reinvented the musical for the Age of Aquarius."  Pauline Kael wrote a review applauding the film: "A great movie musical. Taking its form from political cabaret, it's a satire of temptations. In a prodigious balancing act, Bob Fosse, the choreographer-director, keeps the period--Berlin, 1931--at a cool distance. We see the decadence as garish and sleazy; yet we also see the animal energy in it--everything seems to become sexualized. The movie does not exploit decadence; rather, it gives it its due. With Joel Grey as our devil-doll host--the master of ceremonies--and Liza Minnelli (in her first singing role on the screen) as exuberant, corruptible Sally Bowles, chasing after the life of a headliner no matter what; Minnelli has such gaiety and electricity that she becomes a star before our eyes."  In 2013, film critic Peter Bradshaw listed Cabaret at number one on his list of "Top 10 musicals", describing it as "satanically catchy, terrifyingly seductive ... directed and choreographed with electric style by Bob Fosse ... Cabaret is drenched in the sexiest kind of cynicism and decadent despair."
