Ash the Android (Ian Holm), Alien
''He's so unexpected, he's so genteel,'' says Whedon. ''When he says [of the alien], 'I admire its purity,' I saw a piece of humanity that I'd never seen before. All of a sudden, everything he did made perfect, logical sense.'' But why not choose Sigourney Weaver's Ripley? ''In Alien, you don't necessarily look to Ripley and go, 'Well, she's going to make it, because she's got something nobody else has,''' he says. ''You're pretty sure Tom Skerritt's going to make it out of there, because he's a strapping, handsome man. Ripley in Aliens became [the main hero]. But in Alien Ian was the one who really stayed with me.''
