The film, directed by Oscar winner Kevin McDonald and produced by multiple Oscar nominee Ridley Scott is stitched together from user-generated content and depicts one day of life on Earth from the perspective of 25 people living on it.
All of the events shown in the movie take place in one 24-hour period on July 24, 2010. According to an article in National Geographic, this particular date was chosen because it was after the World Cup, but before the holidays. More than 80,000 videos of that day containing 4,500 hours of footage were uploaded to YouTube. Every single submission was watched and considered for inclusion.
