I never realised 'The Return' would take so long to make - it was a very tough 'political experience,' and the post production in L.A. seemed to go on forever.
We spent four days filming in a helicopter. I had never seen London from that viewpoint - you get a sense of how big it is and how easy it is to get lost. There was one day when we couldn't find Brick Lane: we spent 25 minutes looking and then realised it was directly below us.
