The LA Times has a new interview with Rupert Grint.

“I was thinking about what it’s going to be like when we’re done, after the last movie,” Grint said. “It is going to be really weird, actually. At the moment it seems quite far away. I don’t know what I’m going to do, really. I’m going to miss it, I think, because it’s been my whole life for a long time. I really enjoy it as well, every year we’ve come back and done it. All of this, this is what I know…”

“Dan is the one who is very driven; he’s ambitious and he’s knows there’s quite a few things down the road. I am a little bit more laid back. And Emma, I mean, she’s really cool. We all get on really well; she’s just a really good mate. A great person.”

Grint said Watson is “like a sister,” which made for some awkward scenes in “Half-Blood Prince.” A major component part of the film is young romance, in particular the pained love triangle involving Grint’s Ron, Watson’s Hermione and newcomer Jessie Cave as the smitten Lavender Brown. That provides a lot of this installment’s surge in humor, as does Ron’s bid to become a Quidditch player.
