After gaining much attention at Sundance, Berlin and SXSW film festivals this past January, YouTube’s Life in a Day movie is now available on YouTube, according to the official YouTube blog.

The stunning film, which we reviewed after its London premiere, was directed by Oscar-winning Kevin Macdonald, who took over 80,000 submissions and 4,500 hours of footage from 192 countries and created a feature-length documentary reflecting people’s lives on the 24th of July, 2010.

While over 70,000 hours of uploaded video was user-submitted, the team sent 400 cameras out to the developing world to capture 20-30% of the final film. “We filmed the people who don’t have Internet or cameras in order to paint a global picture. I didn’t want a global film that’s just about rich people, or Europeans and North Americans,” said Director Kevin MacDonald.
