Daniel Radcliffe spoke to the LA Times earlier today, apologising for his notable absence at Comic-Con, where a clip from Deathly Hallows premiered, and discussed the fun time he had in Russia for his 21st birthday this weekend, as well as how he and Harry Potter costars Rupert Grint and Emma Watson were in tears on the last day of filming Deathly Hallows.

"I apologize to all the wishful thinkers for my disappointing non-presence," Radcliffe said.

"Really? Oh, God, I had no idea. I suppose it's like when I'm at Reading Festival I hear that suddenly some amazing band is going to play a surprise gig and then it turns out to be total fiction."

"It was fantastic. I was in St. Petersburg for my birthday, which is probably the most beautiful, the most incredible, wonderful place I've ever been in my life. It really is absolutely amazing. I went with two friends and it was brilliant."

"You know what, I'd love to libel him and call it a lie, but, darn, he's absolutely right. We all three of us -- me, Rupert and Emma -- we just wept. And I've never seen Rupert Grint cry. That was really weird."

"I've never done the Comic-Con thing," Radcliffe said, "and I really, really want to experience that."
