This is another of Alec Guinness' comedies from the Ealing Studios. He plays a scientist so difficult and egocentric that he can't get a job in research, so he gets janitorial jobs and sneaks into research labs, trying to make a miracle synthetic fabric...and when he succeeds, finds that nobody thinks it's a good idea.

Guinness is, of course, wonderful, and the rest of the cast is good. As a portrait of postwar Britian's labor/union problems it's interesting, and their version of research labs is also worth seeing. And I loved that the London Philharmonic did the music, including the blup-blup noises that the machines made, that was so cool!

This is not a laugh-out-loud comedy, but is rather low-key and bittersweet; Guinness is odd and not very likeable, except that he is so sure that his vision can come true that you can't help but hope it does.
