The footage for the film was shot both by the public using mobile devices as well as up-and-coming filmmakers. Lee guided and directed the creative submissions through video messages and blog entries. On the film, Lee said: "The new technology, you might say, is bringing a democracy to film. Anyone can be a journalist, a filmmaker, a still photographer. Just pull out your mobile device, record it, press a button, and it's instantly on the web. So I think it's great that Nokia had the vision to see where all of this is headed. "
