Every day, 6.7 billion people view the world through their own unique lens. Imagine if there was a way to collect all of these perspectives, to aggregate and mould them into the cohesive story of a single day on earth.

That’s what YouTube wants to do as it launches “Life in a Day,” an ambitious but incredibly compelling project which sets to out to document one day, as seen through the eyes of people around the world.

On July 24, you have 24 hours to capture a snapshot of your life on camera. You can film the ordinary – a sunrise, the commute to work, a neighbourhood footie match, or the extraordinary – a baby’s first steps, your reaction to the passing of a loved one, or even a marriage.

Kevin Macdonald, the Oscar-winning director of films such as The Last King of Scotland, Touching the Void and One Day in September, will then edit the most compelling footage into a feature documentary film, to be executive produced by Ridley Scott, the director behind films like Gladiator, Black Hawk Down, Thelma & Louise, Blade Runner and Robin Hood.  LG Electronics is supporting “Life in a Day” as a key part of its long-standing Life’s Good campaign and to support the creation of quality online content that can be shared and enjoyed by all.

The film will premiere at the 2011 Sundance Film Festival and if your footage makes it into the final cut, you’ll be credited as a co-director and may be one of 20 contributors selected to attend the premiere.
