The collaborative film One Day on Earth  was filmed all on the same day, October 10, 2010, with more than 3,000 hours of footage sent in from all corners of the world, showcasing the amazing diversity, conflict, tragedy, and triumph that occurs in one day. The Global Screening  will take place on Earth Day (April 22, 2012) in every country of the world, with the assistance of World Heritage Sites and the United Nations.
You can view the footage sent in through the interactive map on the One Day on Earth archive  for videos recorded during October 10, 2010 and November 11, 2011 by collaborators worldwide. The archive is searchable by tags and keywords as well as through browsing on the map to view the different video clusters.
You can participate in the Global Screening by signing up to assist to one nearby, suggesting a location or hosting an event. In some places, assistance will be limited by the size of venue: to guarantee yourself a spot for the screening, you can sign up on the site.
