Carry On Up the Khyber (1968)

Continuity mistake: During the battle towards the end of the film, Sir Sidney Ruff-Diamond tells Captain Keene to line up his men and you can see that the collar on Keene's uniform is fastened. In the next shot, Keene is fastening up his collar again.

Sir Sidney Ruff-Diamond: Tell Major Shorthouse to call me an elephant.
Lady Joan Ruff-Diamond: He needn't bother I'll do it. You're an elephant.

Trivia: During the dinner scene towards the end of the film, a piece of plaster falls from the ceiling onto Lady Ruff Diamond who says, "Oh dear! I seem to have got a little plastered!" Joan Sims ad-libbed this line.
