Ridley Scott and Kevin Macdonald are teaming up with YouTube to make what is being called the “first user generated feature length documentary film shot on a single day.”

Director Kevin Macdonald is calling for YouTube users from around the world to upload footage of their daily lives on a single day - 24 July - which will then be edited together into a feature length documentary, entitled Life In A Day. Sir Ridley Scott will produce for his company Scott Free Productions.

Life In A Day will have its premiere at the Sundance Film Festival in January 2011. Users whose footage is included in the film will be credited as co-directors, whilst YouTube has promised to fly 20 of them to the Sundance premiere.

Macdonald, whose credits include The Last King OF Scotland and Touching The Void, described the project as “a time capsule that will tell future generations what it was like to be alive on the 24th of July, 2010.”

“It is a unique experiment in social filmmaking, and what better way to gather a limitless array of footage than to engage the world’s online community,” he added.

The project is the latest effort by YouTube to support projects that combine online video with the arts such as YouTube Symphony Orchestra and its recently announced YouTube Play partnership with the Guggenheim.

“Over the past five years, YouTube has changed the way media is created and consumed,” said Eric Schmidt, CEO of Google, YouTube’s parent company. “We’re thrilled to give our community the opportunity to work with Kevin Macdonald and Ridley Scott and are grateful to our long-term partner, the Sundance Institute, for their support of this global initiative.”
