The documentary is the first-ever collaboration of simultaneous filming occurring in every country of the world, and is to be screened at venues across the globe on April 22.

The film was produced from 3,000 hours of footage shot by people all over the world, from students with cellphones to professional filmmakers on Oct. 10, 2010.
