New interview with director David Yates

I really love the humor. I like humor. I think it leavens the load a little bit, and Dan, Rupert and Emma do it quite well. Even though the next script is quite intense, and Steve's really great at pairing it with little moments that are quite charming. They're not gags. They're just really delicate funny humorous bits. Then I'll throw in a few things, like the scene with the pies when Rupert sits down. That was just a bit of improvisation. There was just a big plate of pies and I went, "Rupert, I know what we'll do, let's try this" and then Steve writes a lot of really funny stuff which I adore, and the guys adore doing. I think we need to keep that. I think audiences enjoy it, it keeps them in the right mood.
