"The Day the Earth Stood Still", directed by Robert Wise

Movie, 1951

Cold War science fiction film which despite its reliance on formulae, repetitive stock footage (or what looks like stock footage) and fairly rudimentary special effects, sets down a message which focuses less on the reds under the bed and more on the innate human quality for self rather than mutual destruction. As a result, the film is pretty bleak and can feel preachy, but must have seemed nuanced at the time of its release. It still carries a punch in 2017. Overlook the naivety here and there, fall into the period and this is an enjoyable, cautionary tale.
