Documentary director Kevin Macdonald and producer Ridley Scott want to use YouTube to turn a camera on the world. The will make ‘Life in a Day’ – using nonfiction video submissions that will provide a snapshot of a 24-hour period around the world.

The idea is to encourage people around the world to take out their cameras on July 24, shoot some footage and upload the results to YouTube. There will be no editing required. Macdonald will sift through the entries and create a full-length documentary using the clips as raw material. The final product will be shown at the Sundance Film Festival in January.
