Answer
Zulu, a 1964 British war film, features Mangosuthu Buthelezi in the role of King Dinuzulu. The film depicts the Battle of Rorke's Drift, where a small British garrison successfully defended against a large Zulu army in 1879. Buthelezi's portrayal of King Dinuzulu, the leader of the Zulu nation, adds depth and authenticity to the film's historical narrative.
