“As for the idea of using a British accent, Stevens revealed, “I checked in with Noah [Hawley] when he sent me that scene, and I was thinking of different ways of distinguishing [the two Davids], and I was like, ‘Well, it’s kind of a little nod to the Professor X thing,’ which we’ve kind of laced again through the series without getting too explicit. There are definitely rewards for people who know the comics. I don’t think at any point we’re directly adapting any story, or even any frame of a comic, but the paradigm exists. So this idea of characters being locked in there, of a battle for control over David and his powers, of this ongoing throughout history kind of thing… We use that and borrow that. But the British thing, I said to Noah, ‘Well, what about if we make him British?’ And he immediately was like, ‘Yeah, I guess deep down all of our rational selves are probably British.’ I was like, ‘Oh, good. That sounds like an endorsement, so I’ll go with that.’ I’m not sure how true that is, but anyway, it seemed funny to me!””
