Chris Milk’s work straddles experimental genres and unfamiliar mediums, turning emerging technologies into newfound canvases. In recent years, Milk has focused on using cross-media innovations to enhance human storytelling. The Johnny Cash Project, The Wilderness Downtown with Arcade Fire, and Sound and Vision with Beck use breakthrough technologies to tap into the intensely personal, emotive power of music and create visual experiences that are globally interconnected, yet individually meaningful for each participant.

Since the film was released, the production company rebranded as Here Be Dragons, which is a much better name than their old one.
