EDITOR’S NOTE: Battle Beneath the Earth was on the CBS Late Movie on May 1 and September 26, 1972 and December 21, 1973.
Scientist Arnold Kramer (Peter Arne) really does think if you dig deep enough you’ll make your way to China. He thinks that Chinese General Chan Lu (Martin Benson, not Asian, but Russian/Polish; he was famously in The King and I, playing the gangster who Oddjob kills in Goldfinger and was also Prostetnic Vogon Jeltz on the British TV version of The Hitch Hiker’s Guide to the Galaxy) is planting nuclear bombs under the United States but no one believes him. They put him in a mental hospital before Navy Commander Jonathan Shaw (Kerwin Mathews) comes to meet him and reveals that he thinks its true; they head down into tunnels built into Hawaii and go to war.
The last movie directed by Montgomery Tully (The Terrornauts), this was written by Charles F. Vetter.
A bad guy with a falcon, everyone with a British accent and Ken Jones did a great jazz score. Those are the best things I can say for thio, other than if you have to be in a hospital, make sure its one that has slot machines.
