Disney have produced this charming short animation telling the story of a chance encounter at a train station and the struggle and desire to seize this moment and convert it onto something more meaningful. FX Guide has an in-depth look at the story behind the short, including detail on the technical considerations in achieving the painterly 3D look.
What the article doesn’t discuss, but was something that struck me, was its suggestion of the paintings of Edward Hopper in both the use of light, and the framing of shots through window openings; the young woman on the train as seen from the platform, the young woman in the office as seen from the outside, the young man in the office as seen from the outside. Then, as the credits roll, we see the young couple sat within a cafe, framed by the large window and a view of the sunny exterior. At least here (and this is Disney after all) we are provided a happy conclusion. In the work of Hopper, the characters are usually alone and never happy.
Update: Paperman won the Oscar for Best Animated Short at last nights Oscars!
