The 33rd Cannes Film Festival was held between 9 and 23 May 1980. The Palme d'Or went to the All That Jazz by Bob Fosse and Kagemusha by Akira Kurosawa.

All That Jazz is a 1979 American musical drama film directed by Bob Fosse and starring Roy Scheider. The screenplay, by Robert Alan Aurthur and Fosse, is a semi-autobiographical fantasy based on aspects of Fosse's life and career as a dancer, choreographer and director. The film was inspired by Fosse's manic effort to edit his film Lenny while simultaneously staging the 1975 Broadway musical Chicago. It borrows its title from the Kander and Ebb tune "All That Jazz" in that production.
