This short film is really interesting and we can see and other "Nolan's touch", what I mean is that in this short film we are strongly focus on the character thanks to the mise-en-scène and the visual effects. A things that we can see in lot of his film like Memento or The Prestige and also Insomnia.
This short film is on youtube if you want to see it (but in a really bad quality). Or it's on the dvd Insomnia (at least in french edition)
Doodlebug gave me a good chuckle. It's okay, not fantastic. It's a small concept and you see that even in such smaller scope film ideas, Nolan plants interesting themes. Still, it's alright but I'm not exactly blown away.
