Question: If you see David Boreanaz at the Fox party, ask him if there's any chance of a Buffy-Angel reunion movie."” Karisma
Ausiello: It's been well documented that the Big B detests talking about his vampire past, but I bit the bullet and asked him anyway. Although he didn't come out and say it'll be a cold day in hell before he takes part in such a project, it was heavily (and rather uncomfortably) implied. You can judge for yourself when the video goes up.
