Alec Guinness stars as Sidney Stratton, an industrial chemist who believes he is on the path to creating a new synthetic fibre that never wears out and cannot be damaged, dirtied or stained. When at last he succeeds, he finds himself on the run (in a demonstration suit made from the new fabric) from the vested interests who want it suppressed because of the effect it will have on the existing industry.
This film provides examples of:
- Clothing Damage: Averted. Sidney's suit is impeccable, resistant to wear and tear. Therein lies the problem for industry and consumerism.
- This ends up being a subversion, as his revolutionary fibre starts to self-destruct and breakdown after a period of time.
- The End... Or Is It?: The film ends with Sidney walking off down the street while the owner of the textile mill he worked at reflects with relief that he's no longer a threat. Then Sidney has an inspiration about how to prevent the wonder fabric self-destructing...
- Gaussian Girl: Particularly noticeable in the seduction scene when the camera cuts back and forth between crystal-clear shots of Sidney and really really fuzzy shots of Daphne.
- Mad Scientist Laboratory: Sidney isn't mad, just a bit eccentric and unworldly, but his bench of bubbling chemicals hints at his oddity and scientific focus early on.
- Man in White: Sidney, once he dons the new suit. On the literal level, it's white because it repels all dirt and stains; symbolically it represents Sidney's moral innocence in a world of division, corruption and compromise. (Daphne remarks that it makes him look like a modern-day knight in shining armour.)
- Person with the Clothing: Sidney is...
- Pet the Dog: The angry mob rejoice when Sidney's miracle suit is no more, and he's left with nothing. They then realize he only wanted to make the world a better place, and immediately dress him in a good old fashioned suit.
- Sharp-Dressed Man: Sidney's suit really stands out. in this black & white flick.
- Sharpened to a Single Atom: It's not emphasized, but it's mentioned in passing in the dialogue about the development of the new material that the threads are, in effect, molecular monofilaments — which causes problems in handling and cutting them. It evidently doesn't occur to any of the characters that this could have other applications (though Sidney does later use them as a reliable rope when escaping from an upper-floor room by climbing down the wall). This may be one of the earliest occurrences of the concept in fiction.
- Trick Dialogue: Sidney delivers an impassioned speech about why he shouldn't be fired for using company resources on his quest — to the mirror in the men's washroom.
