Oscar-winning actress Angelina Jolie has financed a documentary that has people all over the world simultaneously capturing events as they occur during a three-minute timeframe.

Jolie, who has adopted Cambodian orphan Maddox, came up with the idea for "A Moment In The World" after realising how contrasting her travels have been in recent years, celebrity portal Femalefirst reported.

She said: "I kept going between Mad's country and refugee camps or war zones to Hollywood and all these odd places and then seeing the world at all these different times.

"Then it became this kind of crazy adventure of organising a lot of people and gathering over 30 crews of people and sending them across the world to all these places," she said.

"On January 11, we all opened up our cameras at the exact same time, coordinated across the world for three minutes."
