I just listened to David Boreanaz talk with the BBC about I don't even know what. The important thing here is that the DJ seems to be Scottish and for some reason DB feels the need to embrace his inner Liam in this chat - I never thought I'd hear that "unique" accent again and you all know what I mean by "unique". The scary thing is that I'm not even sure if he realizes it. He also does some speed dating thing which I don't quite understand and if you skip to around 12-13 minutes in, he answers the Buffy Movie question.
Go here to listen.
