Ridley Scott is behind it and to cut a long story short, it's 80,000 clips (45000 hours) of footage cut into a 90-minute
fly on the wall documentary (shot by the people) about everyday people and their life. The best bits make it into the
movie. You can hear Ridley speak about the project in the clip at the bottom of this post.
From a digital data, information tech point of view, I think what these guys have done below is very cool!
