Apocalypse How? - Battle beneath the Earth (1967)

My latest visit to the world of impending doom is this piece of classic cheese, courtesy of MGM.

"Battle beneath the Earth" was released in 1967 and, as the time it was released was during one of the most unstable periods of the Cold War, its chock full of bizarre paranoia about impending invasion by those DIRTY COMMUNISTS!111!1!1!one!1!!11111!!!, except this time round, instead of being of the Russian variety, instead it offers up a dose of Chinese commie related laughs.

Starring no one I've ever heard of, apart from Ed Bishop, this sci-fi film really takes the plot line to the edge of believability:-

The US Navy has been tinkering with some seismic devices in an effort to detect underground nuclear tests from within the communist bloc, however their experiments cant seem to make a device capable of accurately differentiating between the sound of a nuclear explosion and the sound of mining operations.
All this is rendered moot when a man is picked up by the police in Las Vegas  after raving in the street about sounds he can hear when he puts his ear to the ground, however his insane/drunken ravings are soon proved to be rather worrying when coal miners discover a series of tunnels by accident after a mineshaft collapse.
The marines go in and find that deep underground, some rogue Chinese agents have spent a lot of time digging tunnels which lead all the way from China to the US, and have begin planting nuclear bombs under most of Americas major cities.
The marines manage to safely defuse the first lot they find, however those slippery commies have more nasty tricks up their sleeves, tricks which, they hope, will lead to the complete downfall of the free world and the global domination of the Chinese empire.

Yeah, they don't make sci-fi silliness like this no more, which is a shame. Nontheless though, this film is a classic bit of cheese which will require you to leave your sense of logic at the door when watching, but trust me, if you do this, you will find this film a fairly entertaining way to kill 90 minutes.
