BICYCLE MESSENGERS is a short film in which all of the messengers are animated and all of the backgrounds and environments are live-action footage shot in Midtown Manhattan. By juxtaposing the animated characters on top of the live action, the film highlights the peculiar relationship between bicycle messengers and the modern city in which they operate.
