Bottoms Up! (1960)

An incompetent boarding school headmaster, Professor Jim Edwards, devises a bizarre plot to raise the profile of his boarding school, and thus save his job, by passing off his bookie's son as a Middle Eastern prince. The headmaster's madcap scheme is further complicated when an official from the Foreign Office arrives and announces that a real prince is to be placed under Edwards supervision, not due to the schools lofty reputation, but that a gang of kidnappers are unlikely to look for the regal child there.
