Angela Douglas makes her fourth and final appearance in the series. Terry Scott returned to the series after his minor role in the first film of the series, "Carry On Sergeant" a decade earlier. The film is, in part, a spoof of Kiplingesque movies and television series about life in the British Raj, both contemporary and from earlier, Hollywood, periods. The title is a play on words in the risqué Carry On tradition, with "Khyber" (short for "Khyber Pass") being rhyming slang for "arse".
