The original Keep Calm and Carry On propaganda posters were created to provide guidance to British citizens should Germany invade.
Yet the war has passed and times have changed. Britain – and the world at large – faces new threats. Extraterritorial threats. Silent threats.
The Silence, so named because they move among us without our explicit knowledge, in silence, always to be forgotten when they are out of sight.
So if an alien race invades the Earth without us even knowing or remembering: Keep Count and Shoot First.
British war-time Keep Calm propaganda poster meets Doctor Who in the British mash-up.
