Ninety Degrees in the Shade (Czech: Třicet jedna ve stínu) is a 1965 British-Czech drama film directed by Jiří Weiss.

That night also, we see the unhappy home life of the meticulous inspector – his alcoholic wife and lazy son.

Variety wrote that the film: "has has quality, mainly because of the shrewd and observant direction by Jiri Weiss, who is probably the most internationally known and respected of all Czech directors.

It is largely thanks to this thoughtful direction that the film does not wind up as a trite, cliche-ridden piece of celluloid, but as a meaningful drama, in which emotion plays a larger role than reason in the life of a young and attractive woman.

In less competent hands, this might well have been just a novelettish yarn, though some recognition is also due to David Mercer's sensitive seript.
