Picking the right guy to play Obama, that was the challenge, I mean, who is Obama really? We don’t know. We never got his transcripts and they say he’s kinda aloof. So I needed someone who could really dive in and really become Barack Obama and as it turns out, the answer was right in front of me all along: Daniel Day Lewis. He becomes his characters – Hawkeye from ‘The Last of the Mohicans’ and Bill the Butcher from ‘Gangs of New York’ and Abraham Lincoln in, ‘Lincoln’. And you know what? He nailed it.  - Steven Spielberg (x)
