Warren Ellis watched Bullet Train.

Chekhov’s gun is a writing principle that states that everything in a story should be there for a reason. Chekhov’s famous example is that if we’re told a rifle is hanging on the wall in chapter one, then someone needs to fire it in chapter two, otherwise why tell us there’s a rifle there?  Chekhov tells us not to waste time with details that aren’t important.  Talk about only what is in service to the story, no matter how irrelevant it may seem at the start.

I saw Bullet Train a while ago. The actors’ joy was contagious.
