In the 15th proper 'Carry On', 1968's "Carry On Up The Khyber" (again under director Gerald Thomas & writer Talbot Rothwell) Sid James (married to Joan Sims) is the British Empire's ruler over an Indian region on the Afghan Border (actually filmed in North Wales) protected by Roy Castle & Terry Scott's regiment. But when the regiment's fearsome reputation is ruined (by Charles Hawtrey's skiddies) the locals under Kenneth Williams (with daughter Angela Douglas) & Bernard Bresslaw (terrific again) revolt, and the Brits must fight back (aided by Peter Butterworth). It's raucous, daft, harmless fun... and one of the most famous in the iconic Brit-com series.
