From The Los Angeles Times:

“Life in a Day” is a groundbreaking film produced by Ridley Scott and directed by Kevin Macdonald that solicited user-generated content from around the world that was shot on July 24, 2010. With more than 80,000 videos from 197 countries, 4,500 hours of video was edited into a 94-minute portrait of the world. Google and YouTube have released the full-length feature for viewing before the release of the DVD
