Noor Agha, who lives in a graveyard in a rubbish-strewn in Kabul district is the unlikely hero behind the scenes of The Kite Runner, one of Hollywood's most eagerly anticipated movies this year. Agha, widely acknowledged as the best kite maker in Afghanistan, has spent weeks training the movie's teenage protagonists in kite flying and duelling, skills they used on camera when the movie was shot in China last year.
