Nicholas Hoult has asked for a moment to think, because I've caught him off-guard with a question about his desert-island smells (in fairness, we are here to talk fragrance for Emporio Armani) and he is taking it very seriously indeed. He begins: "Yeah. I mean just anything being roasted or cooked. Fresh baked bread ... that smells pretty good, doesn't it? Maybe a hint of rosemary."
