I tried my best to evoke a John Carpenter vibe to this one. I watched lots of old 1970's horror trailers (beyond the obvious The Fog which this is riffing on) to make sure this struck the right tone. Was fun to revisit Edgar Wright's Grindhouse trailer Don't. Such a perfect pastiche of those sort of trailers. I had written a slightly more righteous and serious piece about air pollution in the UK for this, but my editor correctly steered me in a lighter direction.
