Story line provides adequate excuse for a Carry On foray into the Foreign Legion territory, with a young hero (Jim Dale), accused of cheating at cricket, enlisting with his manservant to exculpate his disgrace. There he encounters Phil Silvers, as a sergeant who invents acts of heroism and is much decorated, Kenneth Williams as the German commanding officer, Charles Hawtrey, as his deft adjutant, and Joan Sims, as a much-cleavage siren.
They are involved in running skirmishes with an Arab chieftain, serving a master called Mustapha Leak, and the farrago climaxes in a hilarious battle at a desert fort, after a forced march through waterless wastes.
It all works with considerable bounce, with elements of parody of Beau Geste-style movies for those alert to them. All the regular comics are on first-rate form.
