LOS ANGELES  - Twenty-six spontaneous filmmakers from around the world will be heading to the Sundance Film Festival in two weeks, all for the same project: "Life in a Day."

The experimental crowd-sourced feature will have its world premiere at the Eccles Theater on January 27.

YouTube and Scott Free UK produced the project, which originated from an invitation to people around the world to send in footage they shot on July 24, 2010.

Scott Free worked with Rick Smolan, CEO of Against All Odds Prods., to distribute cameras to remote regions of the world to make sure the film was as inclusive as possible.

"Last King of Scotland" director Kevin Macdonald has spent the last six months with his team directing and editing the 4,500 hours of footage from 192 countries into a contiguous feature that will screen as part of the Premieres section of the festival.

All of the contributors whose footage was used are credited as co-directors, and 26 have been invited to attend the premiere.

YouTube will also live stream the film and then rebroadcast it the following day at 7 p.m. in their local time zone, subtitled in 25 languages.

Festival director John Cooper will moderate a global Q&A with Macdonald and the 26 filmmakers after the premiere.

"The process of making 'Life in a Day' has been such an inspiring one for me and my team, who helped view and log all 4,500 hours of footage we received," says Macdonald. "Every day, we felt like we were seeing 20 different possible films as we got insights into so many people's lives. It is a testament to the skill, insight and generosity of so many contributors that we have ended up with such a powerful, cohesive and emotionally engaging film."
