Audio problem: When Sid James comes out of the building, in the scene at the end with the big fight, a man comes up to him and Sid asks, "You wish to see me?" Just before this, you see him mouth the words to that line.
Carry On Up the Khyber (1968)
1 audio problem
Directed by: Gerald Thomas
Starring: Kenneth Williams, Sid James, Charles Hawtrey, Sidney James, Roy Castle
Continuity mistake: During the bombardment of the British Consulate, there are several continuity errors, including a self-repairing window and blind situated behind the piano. And it cannot be put down to the nature of the film because several errors have been carefully avoided.
Brother Belcher: Don't worry - we'll save you some Strawberry Mousse.
Trivia: The Khyber Pass is actually Snowdonia in Wales. All of the rest of the production was filmed at Pinewood Studios in London.
