The short is shot entirely in black and white and has been created using both CG and traditional hand-drawn animation. As you can tell from the images, the effect is incredibly beautiful and has a touch of film noir to it.
Disney were pioneers in short form animated film-making when Walt was alive, but in recent times they've been overtaken by Pixar. It's encouraging then to see them pushing Paperman with not just these images, but also a Facebook page and a short interview with Kahrs.
Paperman will be released to the general public alongside Wreck-It Ralph in November, but festival crowds will be able to catch it at the Annecy International Animated Film Festival in June. It looks well worth seeking out.
