Something of a New York equivalent to Stephen Frears' Dirty Pretty Things in investigating a minimum-wage, multinational workforce struggling to get by unnoticed amid hectic metropolis life. The difference is that Frears is an established English director who had the odd star name in his cast.

This winner of best film at the London film festival is written and directed by Iranian-American Ramin Bahrani and stars Pakistani-American Ahmad Razvi in a tiny, zero-budget film that is reminiscent of the first great neo-realist film Bicycle Thieves (1948) in both style and content, shooting in three weeks often using a concealed camera for the street scenes.

Instead of a bike, our reticent hero has the eponymous cart - what we would call a kiosk - from which he sells coffee and doughnuts, also doing odd jobs to make ends meet. During one of these, the guy employing him recognises him as "the Bono of Lahore". Typically, little is made of this, no flashbacks, no explanation.

The cart pusher has a kitten and a child to whom he can't gain access. He befriends a woman street seller from Barcelona. That's about it. If you're looking for plot and action, look elsewhere, but while this modest little feature risks viewers' boredom, its simple observation is effective at shining a light on unconsidered lives.
