A classic, (and very, very funny) British comedy that seems to have slipped through the net, (despite having been picked up and remade last year with Billy Bob Thornton). Aficianados, of course, love the film with a passion and for good reason since it represents a high point in the careers of Ian Carmichael, Terry-Thomas and director Robert Hamer, (sadly this was the last thing Hamer did).

It's based on the Oneupmanship books of Stephen Potter, in themselves classics of British humour, and here Potter is played by the great and inimitable Alastair Sim, though Sim takes a back seat in this one. Surprisingly, the writers Hal E Chester and Paricia Moyes, who adapted Potter's books, have managed to pull together something of a coherent plot rather than just a series of sketches as initially nerdy Carmichael starts putting Sim's Dark Arts into practice as he goes head-to-head with the dastardly Thomas for the virtue of Janette Scott. Anyone who has ever wondered what the point of Terry-Thomas was need look no further than here. He's a comic fireball and he ignites every scene he's in. Seek this one out.
