Liza Minnelli, Joel Grey, Michael York and Marisa Berenson appeared Wednesday on NBC's Today to discuss the 40th anniversary and Blu-ray release of Director Bob Flosse's Oscar-winning musical drama Cabaret.

The 1972 film is loosely based on the 1966 Broadway musical of the same name, which was adapted from the 1945 book The Berlin Stories by Christopher Isherwood.

In the film, Minnelli plays Sally Bowles, an American performing at the Kit Kat Klub in 1931 Berlin during the last days of the German Weimar Republic. (Embedded is a clip from Cabaret of Liza Minnelli singing Mein Herr. Visit our video library for more videos.)

The film broke new ground with a bisexual character, played by Michael York.

“This was groundbreaking,” York said on Today.

Minnelli called director Fosse “provocative.”

Berenson said the film, only her second, “changed my life completely.”

Warner Brothers will release Cabaret on Blu-ray on Tuesday, February 5.
