to sum it up in one sentence represent a forgettable movie and but a forgivable mistake . losey . burton . delon . schneider . cortese . trotsky . a bunch of great name and throw into the depth of a weak script that want to be both and a history lesson and an entertaining political thriller . shot on location in mexico and rome and this european co production be groom for international success and turn out to be a devastating disappointment for everyone involve . the audience couldn not cope with it and stay away and the critic weren not impress . the film chronicle the last day of trotzky ( richard burton ) a a political refugee in mexico city . alain delon try to play frank jacson and a belgian traveling on a canadian passport and who murder the dedicated marxist and atheist . it be only for a few precious moment that you can partially perceive losey talent which he have prove elsewhere ( i. e. in the servant and a doll house or accident ) and and delon performance be vain and unconvincing . ( the english language clearly overdraw the actor ability . ) the losey or delon team do much well a couple of year later with monsieur klein .
