This may only be a one minute short film, and yet it carries a lot of significance when looking at the career of Satoshi Kon. He died of pancreatic cancer in 2010 and finished his last feature, Paprika, in 2007. But in the intervening years (aside from another film, The Dream Machine, that remains uncompleted) he made this, 'Good Morning', for a Japanese TV show. Why he contributed it, I have no idea. But it has a very simple concept - almost what you might expect in a student film - and executed flawlessly.
It's the ideal short film in a way as you see a person getting ready to start their day (and including a fluid animation style that was par for the course for Kon by this time), and the woman subject is a double of herself following her around. So you get to see this 'real' person and then the 'fake' following her, as if it's the part of her that isn't really ready to get started with the day, or is an apparition. And yet it's still a story told and every frame seems lovingly crafted, without a moment missed to make something graceful in how the woman moves despite (or because of) her sluggish-getting-ready-for-the-day routine.
