I don't have a problem with him being quite young. If Harry's parents were about 21 when he was born (I forget), they'd only be 38 now, along with Snape and Remus. Taking into account the fact that wizards seem to frequently marry far younger than muggles, and Luna is a 16 year old only child, why shouldn't he be still be relatively young? I know his hair was white, but that doesn't necessarily indicate old age. He just has to look like wildly eccentric!

What I don't like about this interview is when he said he wasn't a fan of Harry Potter. That could be taken negatively (as indicated by some of the responses on this thread). He may have simply meant that he didn't read the books and follow interviews which is fair enough. However he should have left it at that - admitting he hadnt read the books was enough indication he wasn't a fan, he didn't have to state it so clearly. He frequently acts in 'edgier' roles, maybe he felt HP uncool? That could be unfair, but when he stated his opinions so bluntly, he opened himself up to interpretation.

It just came across as unprofessional. He doesn't need to read the book, Xeno isn't that important. However I certainly hope he read the few chapters his character was in, to get the right flavour. Michael Gambon's character was far more substantial yet apparently he just read the script and based his Dumbledore on that. Bearing in mind how various Hollywood execs always mangled Steve Kloves serviceable first drafts, in order to target various audience groups, it explains how his performance veered away from the books so wildly.

I really hope Rhys Ifan made the effort and read the few pages JKR wrote about his character and didn't depend on WBs script by commitee that is so sub-par.
