"It's categorically not a secret what he is," says Scott about David, explaining that the role is a nod of sorts to Ian Holm's Ash, but that holding onto his identity as any kind of mystery would have been too clichéd. Fassbender, in shaping the character, relied less on memories of Holm, Lance Henriksen and Winona Ryder (!) in the earlier films than recent viewings of Scott's Blade Runner, Dirk Bogarde in The Servant, Peter O'Toole in Lawrence of Arabia and Bowie in The Man Who Fell to Earth. Apparently there's even a bit of the Olympic diver Greg Louganis in there -- something about his weirdly efficient walk. He looks fantastic in it, and so, in a more vulnerable and human way, does Rapace.
