" Ice Station Zebra " released 1968

The Cold War-era movie, Ice Station Zebra, released October 23, 1968, was based on the Alistair MacLean novel of the same name.  It follows the events after a satellite ejects a capsule, containing images captured by an experimental camera from the British, using special film developed by the US, and stolen by the Soviets.  The pictures are those of American missile silos and Soviet missile sites, and the capsule lands near the British outpost Ice Station Zebra. 

Both the Americans and the Soviets are in a race to recover the capsule and the images before the other.  

The movie starred Rock Hudson, Ernest Borgnine, Jim Brown, and Ron Masak, who passed away just days ago.  

Although it opened to mixed reviews and a 49% rating on Rotten Tomatoes, it was nominated for two Academy Awards: Best Cinematography, and Best Special Effects.

I enjoy this movie and have watched it twice.  It's one I don't find on television often but it's always great to watch.  

The Twilight Zone episode "The Midnight Sun" airs 1961

The tenth episode of the third season of The Twilight Zone, The Midnight Sun, aired November 17, 1961.  Norma (Lois Nettleton) and her neighbor Mrs. Bronson (Betty Garde) suffer from an increasingly oppressive heat wave, caused when the Earth falls out of orbit and begins getting nearer to the sun.  

The threat of nuclear apocalypse was a recurring theme in the Twilight Zone, since the Cold War was at its height during this time, but this episode is pure science fiction.  

It also has one of the best twists at the end of any episode.
