He's half American, has a US passport (apparently you do need one to drive an express train down an LA street) and grew up partly in Illinois, but the rhythms of the Big Smoke still run in Nolan's blood. Born in London and an English lit undergraduate at UCL, where he met his future wife Emma Thomas, he still has a house in the city and frequently returns to film. All three Batman movies have had scenes shot in London, while he returned to his alma mater to film Inception's college scene at UCL's Flaxman Gallery. If you want to pick up some meds, Yousef's pharmacy can be found in the Farmiloe Building in Smithfield. Or you could always go to Boots.
