Lawrence of Arabia leapt to mind when I cast Michael Fassbender because I realized that Michael Fassbender, with blond hair is not the same, but not dissimilar to, and if you were ever gonna redo Lawrence you’d probably certainly want Michael Fassbender to be Lawrence.
And I thought, you get a person, a being onboard the ship who is of serious intelligence, probably an IQ of 225 or 300 he’d wanna definitely entertain himself, and by entertaining himself he would naturally educate himself, by watching everything that’s onboard. So he’s been through the entire library of a million movies. The thing that stuck to mind was Lawrence of Arabia which he plays again and again mainly because he loves the anecdotal thinking of Lawrence himself so we go on out and the line is him saying: “The point is not minding it hurts” when Lawrence burns his finger. Which in a funny kind of way has a kind of loose, metaphorical connection to a person who has no soul, has no feelings and in fact is David. So that’s why maybe he gravitated towards Lawrence because Lawrence, in a funny kind of way while he was a very passionate character also had a degree of a soulless quality to him which made him kind of even more powerful. So I thought it was a good connection.
