What is "che!"

Che! is a 1969 American biographical drama film directed by Richard Fleischer and starring Omar Sharif as Marxist revolutionary Ernesto "Che" Guevara. It follows Guevara from when he first landed in Cuba in 1956 to his death in Bolivia in 1967, although the film does not portray the formative pre- Cuban revolution sections of Che's life as described in the autobiographical book The Motorcycle Diaries (1993).
