Panic in the Year Zero (1962)
Harry: Now we don't know what lies ahead of us. The unknown has always been man's greatest demoralizer. Now maybe we can cope with this by maintaining our sense of values, by carrying out our daily routine, the same as we always have. Rick, for instance, and myself will shave every day... although in his case, maybe every other day. These concessions to civilization are important. They are our links to reality, and because of them we might be... less afraid.
They've been making movies about the end of the world for a very long time now, and Panic in the Year Zero is actually a pretty good one that you might want to look up if you've never - we mention it because it's the 112th anniversary of its star Ray Milland today but hell, every day's a new apocalypse, it helps to be prepared. Any Milland fans in the house? He worked for so so very long (almost sixty years) and made a ton of classics but it feels as if he isn't spoken of very much anymore. I always think of him when he was older, circa Dial M For Murder, but get a load at him in his younger days...
