Here is the trailer for Life In A Day, the amazing collaboration project by Ridley Scott, Kevin Macdonald, National Geographic, and YouTube. This documentary film chronicles one day on this planet, and was created entirely from over 4,500 hours of uploaded footage filmed by people all around the world showing what they did July 24th 2010. This might be one of the most important films released in the last decade, if you were to ask me. Its amateur filmmaking at the grandest scale.
