What happens when you send a request out to the world to chronicle, via video, a single day on Earth? You get 80,000 submissions and 4,500 hours of footage from 192 countries. Producer Ridley Scott and Oscar-winning director Kevin Macdonald took this raw material — all shot on July 24, 2010 — and created Life in a Day, a groundbreaking, feature-length documentary that portrays this kaleidoscope of images we call life. National Geographic is bringing it to theaters starting July 24, 2011. Prepare to be amazed.
