To be totally honest, Aneurin Barnard seems like the type of person who might legitimately be a wizard hiding out in the Muggle world (and to be totally fair, a big part of it is that great name he has). Barnard is arguably the lowest profile of all the actors on this list, but he's included because he is uniquely qualified for the role. He has a strangely engaging quality that draws viewers in, even when he's only playing a supporting role. He's probably best known for his work as the famously controversial Richard III in the Emmy-nominated miniseries The White Queen. The Welsh actor is sort of reminiscent of a young James Frain, which is not the worst thing that could be said about someone. He's very much an up-and-coming face that you should be seeing a lot of within the next couple years, so let's get in early and say that he is someone you definitely need to be keeping an eye on. Especially for this role. He very well could be off having adventures following herds of hippogriffs across the countryside at this very moment.
