Red Planet Mars (1952)

An old-fashioned revival of faith sparked by a message from Mars touches an Earth under threat of nuclear war. This probably seems like a silly plot idea to a lot of modern sophisticated people. Except, this is almost what happened in Eastern Europe in our lifetime. Pushed beyond its military-industrial ability by the defense initiatives of Ronald Reagan(also a man of faith), the Soviet Bloc was pushed over the edge as people of faith in Poland, the Baltic republics, East Germany, Czechoslovakia, Hungary, Romania, and even Mother Russia herself protested and pushed toward democracy and freedom. The combination of political, economic, and spiritual forces have reshaped a continent and changed our world. The candles and prayers didn't hurt. "Well done, Simplicity!"
