Miller, who reprises his role as Credence Barebone in Rowling’s franchise sequel, is himself a fantastical creature. A wild and cerebral 26-year-old, who effortlessly straddles arthouse material (like his bruised, menacing, star-making turn in We Need to Talk About Kevin) and commercial work (he’s The Flash in DC Comics’ mega-budget Justice League), he emits eloquent treatises on the future of ‘Planet Earth’ and ‘cosmic’ philosophies (‘I identify with every single faith in the world and none because they’re all f***ed-up. Quote me!’). He spouts Wildean aphorisms: ‘I don’t believe in belief and I don’t believe in people, but I think they’re pretty.’ And he is full of all the peace and love of a flower child: ‘There’s a tiny Buddha baby inside your belly who just wants to laugh, be free and be naked.’ This may sound painfully pretentious but, somehow, it isn’t. Really, it isn’t. Miller is too sweet, clever and authentically outré. In short, he’s a delightful throwback from the blandness of today’s Kardashian-o-sphere to the golden era when stars were larger-than-life.
