Aussie filmmaker Lincoln Fenner wanted to know, in the wake of a global economic crisis, where people might consider curbing their spending by asking, "What's the one thing you can't live without?"

In his new documentary, More 4 Me, Fenner gets answers ranging from designer shoes from well-heeled babes on a city street (one respondent says she has "about 50" pairs) to the simple life-giving necessity of water, from a person in the slums of Nairobi.

Fenner, who is looking for a distributor, visited seven countries on five continents to interview everyone from actors and models to orphans and street sweepers. New York, London, Los Angeles, Singapore, Perth and Tokyo are juxtaposed with a Kenyan orphanage, the slums of Nairobi, and remote Cambodian villages.

Looks like a great lesson in what we value most. Here's the trailer:
