Coraline began as Neil Gaiman's 2002 novella before Henry Selick's 2009 stop-motion film made its button-eyed Other World widely recognisable. At the centre is a locked door in Coraline Jones's new home that opens onto a corridor to a tempting but dangerous copy of her life. Clips evoking that journey have circulated on soundboards and in fan edits because the idea is instantly readable even without dialogue. The portal cue now works as shorthand for stepping through a threshold into a magical, unsettling parallel place.
