Rhys Ifans was interviewed on BBC Radio in Wales last week and a translation is now online. Here is a bit of the interview:

I can’t reveal much about the new Harry Potter film, which I don’t understand because the book is out anyway, but I had to sign a clause that I wouldn’t.  However, I play Xenophilus Lovegood, a wizard who is the father of Luna Lovegood, one of Harry Potter’s friends. That’s all I can really say because I haven’t read the book! There’s been so much money thrown at the project, with there having been [six] other films. They’re filming up in Leavesden near London in an old Rolls Royce airplane engine factory.I’m not a big fan of Harry Potter but it feels like a privilege to get called up with people like Maggie Smith and Michael Gambon so it’s an honour that they thought of me to play a cross-eyed wizard.

Thanks SS!
