Unlike, say, six-foot-six Vince Vaughn, who has a jazzy physical grace that makes him deft at comedy, the New Zealand performer Jemaine Clement is a big guy who looks uncomfortable in his skin. Or maybe he’s not that big (IMDb says he’s six-foot-one) and he just looks like a hulk—large facial features, arms that hang down awkwardly at his sides. The low-pitched Kiwi twang, too, is the voice of a lumberer. But this slow-looking man is a very funny person, as his old HBO series Flight of the Conchords and scattered big-screen appearances—in Jared Hess’ cracked-nuts cult picture Gentlemen Broncos, for instance—have proved.
