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).

(Che is falling behind on a march)
Fidel Castro: Stragglers are sure to die, don't you know that?
Che Guevara: I'm not a straggler, I'm your rear guard.
Fidel Castro: No you're not, you're the company doctor. See what you can do for the men with blistered feet. You've got ten minutes.
Che Guevara: (noticing enemy planes flying overhead) It's too late for chiropody. The buzzards are already circling.
