What was the title of the 1970 documentary about Muhammad Ali's exile?

The 1970 documentary about Muhammad Ali’s exile was A.k.a. Cassius Clay. The film was made while Ali was barred from boxing after refusing induction into the U.S. Army on religious grounds during the Vietnam War era.

Directed by Jimmy Jacobs and produced by Bill Cayton, the documentary looks back at Ali’s rise through the heavyweight ranks. It combines archival footage of fights against Sonny Liston, Henry Cooper, George Chuvalo, and Floyd Patterson with interviews and conversations involving figures such as trainer Angelo Dundee, Malcolm X, and Cus D’Amato.

The title deliberately uses Ali’s birth name, Cassius Clay, which he rejected after joining the Nation of Islam and announcing his new name in 1964. That naming history can cause confusion: the film is not titled Muhammad Ali, and it is unrelated to When We Were Kings, the Oscar-winning documentary about Ali’s 1974 fight with George Foreman. A.k.a. Cassius Clay opened theatrically in 1970 and was narrated by actor Richard Kiley.
