* BannedInChina: The South African apartheid regime only allowed white audiences to see the film because it was thought that it might encourage the blacks to rebel. Eventually, the regime agreed to allow a special screening for the black extras who had been in the movie.

* BeamMeUpScotty: "Suddenly, Zulus! Thousands of them!"
* ExecutiveMeddling: While untrue, rumors circulated of this on a ''governmental'' level: The film company was forbidden to actually pay the Zulus acting as extras, under [[UsefulNotes/TheApartheidEra apartheid]] laws. Director Cy Enfield, who'd struck up a friendship with the Zulus acting in the film, was upset with this and decided to leave them the cattle used in the film, more valuable to them than money. In actuality the Zulu extras ''were'' paid, just less than the white stars, with the main group of Zulu paid 9 shillings, extras paid 8 shillings, and the female dancers paid slightly less.
** Creator/MichaelCaine, who would go on to play working-class Cockney characters throughout his career, plays a snobby aristocratic officer with a posh accent in this movie -- his first.
** Patrick Magee playing the heroic Surgeon Reynolds is quite a departure from his usual typecasting as hammy villains in ''Film/AClockworkOrange'', ''Film/TheMasqueOfTheRedDeath'' and others.
* StarMakingRole: For Creator/MichaelCaine.
