Life in a Day, a feature film created from thousands of videos shot by people around the world, gets its debut at the Sundance Film Festival on Thursday.

While the lucky few in Park City, Utah, can watch it in the cinema, the rest of the world can tune into a live stream of the film (as of 8:15 p.m. ET).

Amateurs and professionals submitted about 80,000 entries to organizers of the massive project. The idea was to chronicle everyday life all over the world on a single day: July 24, 2010. Though seemingly an unwieldy source of material for a feature film, organizers enlisted some high-profile talent, with Blade Runner's Ridley Scott producing and Kevin Macdonald, director of The Last King of Scotland, helming the final product.

Individual videos that appeared on the Life in a Day site reveal some very personal moments, including an Australian man in a hospital bed after a major operation and a gay boy coming out to his grandmother. Trailers also hint at the linking devices used, such as the newspaper that is delivered by bicycle in one country and falls through the slot of home in another.

Macdonald has selected 1,000 clips for the 90-minute film (out of 4,500 hours of footage).

"These clips are about love, they're about life, children, illness, death," he says.

These raw moments of human experience are joined together without narration, with the expectation that reality does sometimes make the best viewing.

National Geographic Films has already picked up U.S. distribution rights.
