Reacher's strength and power aren't a reflection of reality, but Ritchson claimed, "Where [Child] doesn't have to embellish is in his intellect," adding, "The intellect that Reacher has is almost superhero-esque [...] But there's also this kind of dry sardonic humor, and Lee has a lot of that, too." The actor also said that he found Child "gracious and humble and kind and reassuring."
