As an user has pointed out ,this is the last of the spectaculars of the late fifties/early sixties which began with De Mille's "Ten Commandments" and included such works as "Ben Hur" ,"Spartacus " (which was more Kirk Douglas' work than Kubrik's ),the highly underrated "Cleopatra"(when will we see the uncut version?),Mann 's "El Cid" and "Fall of the Roman Empire" .
This is the last hurrah,but it's a bad film.James Mason and Robert Morley do not seem to take their roles seriously (as Chinese characters!!)and their playing is deliciously tongue-in-cheek.But all the others seem to believe in this far-fetched tale ,very dubious historically ,with Egyptian Omar Sharif as the lead who abducts pretty princess (French Françoise Dorléac) who is raped by Irish Villain (even
nastier than Ben Hur's Messala) Boyd.There's also American Wallach who offers him his two daughters.Both Sharif and Boyd seem to enjoy bondage (collar ,cage,etc).When he speaks to common women ,Genghis is feminist (it's up to them to choose) ,but when he is with his wife ,he's a more credible macho.
Incidentally,Sharif,Mason and Dorléac's sister (Catherine Deneuve) would team up three years later in Terence Young's "Mayerling".This time,Mason was Sharif's father .
If you want to see a good Sharif movie,do choose "Dr Zhivago" instead.
