It was conceived on YouTube, born on YouTube, and now it has returned to live on YouTube indefinitely. Ridley Scott and Kevin MacDonald’s crowdsourced documentary Life in a Day brought together footage submitted by thousands of people from around the world as they went about their lives on July 24th, 2010. The filmmakers pored through 80,000 hours of video to find just 90 minutes that would somehow tell a story about life on this planet. The resulting film premiered at Sundance in January and streamed to YouTube at the same time. Now you can watch it in its entirety for free with subtitles in 25 different languages. So what are you waiting for? Check out the entire film embedded after the jump!
