Going way back to 2004, here's one of my favourite all-time short films, Brendan Muldowney's The Ten Steps.
Putting aside my penchant for babysitter stories, I've always thought the payoff in this short was exceptional. Muldowney has since gone on to direct three features, Savage (2009), Love Eternal (2013) and Pilgrimage last year starring Tom Holland and Jon Bernthal.
