"They were always trying to get me killed," Alec Guinness once wrote of The Man In the White Suit's technicians. "They thought actors got in the way of things." He went on to describe how he'd been given a wire rope to climb down and, assured it was safe, narrowly avoided serious injury when it suddenly snapped mid-descent.

"People get in the way of things" might be a maxim tailor-made for White Suit inventor Sidney Stratton (fittingly played blank slate-fashion by Alec Guinness) in Alexander Mackendrick's definitive Ealing film of 1951. Certainly, he cares only about his work, its realisation - and sod the consequences. And similarly, with the exception of a couple of peripheral characters, there's almost nobody to root for in this chilly satire on capital and labour.

Told in flashback, the film concerns Stratton's invention of a dirt-resistant, everlasting fibre (fashioned into the white suit of the title), and subsequent attempts by the clothing industry and its unions to suppress it.

While the industry fears the bottom will drop out of the market, the shop floor stewards worry about finding themselves out of a job. Abduction and bribery attempts follow, with both money and an industry chief's daughter on offer (Daphne, the delectable, 4-packs-a-day-voiced Joan Greenwood), to the tragi-comic end.

"What's to become of my bit of washing when there's no washing to do?" bemoans Stratton's landlady near the close. A notion Stratton hadn't even considered - and has disregarded again by the movie's ambiguous coda.

A superior, if decidedly downbeat comedy, expertly performed - and pretty much answering the oft-raised question of whatever happened to the everlasting light bulb and the car that ran on water...
