In Portal 2, Wheatley (voiced by Stephen Merchant) has some of the best lines. He's witty and when he makes a mistake, he never seems to get flustered. He forges bravely on, never seeming to lose his edge even though he clearly has no idea what he's doing. In fact, he reminded me of "the Doctor" from "Dr. Who." As a bonus, the actor already has a show on the BBC. Does anyone else think he'd be a good choice for the next Doctor?
