Neil Gaiman (Coraline, Stardust) has a lovely poem about the world ending called The Day the Saucers Came that involves an alien invasion, the reanimation of legions of the undead, Viking Ragnarok, angels, time machines, an artificial intelligence uprising and many, many more end-of-days scenarios all hitting at once. Basically, it's the apocalypse to end all apocalypses.
Were anyone to ever turn The Day the Saucers Came into a movie, it might look a little something like Zach Prewitt's supercut of apocalypse movies.
Normally I grow tired watching supercuts. A minute or so in I just start to wonder how someone ever found the time and patience to cut together very specific moments from hundreds of movies just to highlight different people doing the same thing over and over again. That problem never came up with Prewitt's "SUPERCUT: Apocalypse." Maybe it's just because I am such a sucker for movies about the end of the world, but I think it has more to do with this only utilizing about two-dozen movies to show the spectacular downfall of mankind.
Having said that, he's still missing a few scenarios that would have fit in nicely. What about the human-eating plants of Day of the Triffids? Or the chest-crushing, point-of-no-recovery Melancholia? Still, enjoy this calm and cool look at all the ways the movies turn the demise of humanity into glorious spectacle.
