This was Michael Caine's first major movie roll, and he is excellent in it. The narration is by Richard Burton. The Zulu king is played by Mangosuthu Buthelezi, the actual grandson of the character in the film. The score by Michael Barry is so good I found it on the internet and have it on my iTunes library.
Colour Sergeant Bourne stiffens the line.
Also, it presents a refreshingly positive view of the native Zulu tribesmen, who, fresh off a big victory against British regulars, think they'll have easy pickings of only 150 soldiers holed up at Rorke's Drift, a missionary station. 4000 bad ass Zulu Impis cocky from their recent shellacking of the Redcoats vs. 150 assorted Brits expecting to die looked like great odds.
I'll leave it there, but both sides come out quite honorably. I could watch this movie over and over.
