There is a 1965 film called "THE WAR GAME" - singular, not plural -
The War Game (1965)
which contains wonderful information about avoiding thermonuclear blasts across the street by laying down in the street gutters.
Also, rolling a dining table over, facing the blast. Or wait - was that to ward off those pesky Indian attacks? Darn... now I've forgotten!
In either case, there wasn't a good commentary about re-finishing the table's surface after it deflected 50-megaton blasts. I'm pretty certain you'd want to refinish it, though - maybe that's just so obvious THE WAR GAME producers and other world leaders didn't think it necessary to address that.
Or repainting the house. Window shades, too, might need a bit o' straightening.
Another cute American film is ATOMIC CAFE.
After those, a good cheery film like ON THE BEACH should make the world look quite sprightly.
