Although minor plot points separate the versions, all of the versions share a common element of a stolen gem, which one of the Geste brothers, Beau Geste, is thought to have stolen from his adoptive family. This version, unlike the Hollywood movies, stays true to the book, in that the three young brothers join the French Foreign Legion, are later commanded by Sergeant Major Lejaune (not Markov, as in one of the Hollywood versions), and this TV adaptation contains the scene from the book where the surrounded legionnaires defiantly sing Le Boudin. The legionnaires' equipment is spot-on too, right down to the correct mess-tins and bayonets. Filmed entirely in England, at various locations, with its desert scenes filmed in a sand pit in Dorset.
