A real 'winds of change' film, with traditional values crumbling in the heat of pre-revolutionary Cuba. Guinness is wonderful. Discovering an unexpected ability to recognise the real in the game of make-believe, he emerges as master of the situation through the boldness of his fantasies. This mad world, where fictional characters die real deaths and even the Clean-Easy man can't be trusted, has little in common with Le Carré's Circus, but as Guinness' vacuum-cleaner salesman/spy sheds his innocence, he becomes dimly recognisable as an early incarnation of mole-catcher Smiley. Graham Greene's 'entertainment' is only gently macabre and the threats never quite materialise, but the film cleverly captures the confusion of optimism, cynicism and money-grubbing greed of the 'never had it so good' years.
