The Telegraph has a new interview with Half-Blood Prince director, David Yates.

“It’s funny how things change,” he offers. “I felt really self-conscious making this last film. The first time, I didn’t realise how big it was until I got to the premiere and then got to America and saw how massive the release was, and how huge the reaction was. That was when the penny dropped, when I realised that this was such a big thing for so many people.

“Oddly, that meant that when I started this one, I was a little bit warier of everything rather than being more confident. The first time round you just do it; you just go for it. But I have settled in and this one’s quite different from the last one. It’s a little bit more grown up and a bit wittier. It’s a different vibe.”  That vibe requires the main cast to look past the fact that they’ve grown up together (the first film arrived in 2001) and to embrace the changing nature of their relationships (there’s even some on-screen kissing). “I think the cast are getting better and better,” Yates says, “and Emma certainly seems much more confident this time. She really moved on in the last one, but now she’s even more at ease. And Dan, having done Equus, he’s just finding moments and beats that are really surprising and lovely.”
