British rule in 1895 India is threatened when an embarrassing military secret leaks. Despite awkwardness (blackface used for repertory cast villains) this is the high-point of the Carry Ons, a sharp satire drawing on Kipling and siege actioners like Zulu. Still works as a comedy and as an acute portrait of the arrogance of the English, the class system, and of Empire. Of, er, ‘its time’, but recommended nevertheless.
Here’s the trailer.
