That's actually a very good movie, more a journalistic procedural than a sci-fi movie as reporters in London try to discover why the weather is getting hotter and hotter and government leaders are stonewalling. Turns out simultaneous Russian and US nuclear tests on opposite sides of the world have wobbled earth out of orbit and it's now circling the drain into the sun.Nonsense, of course, but a good movie nonethless. Featuring a young(er) Leo McKern.
