Ooohhh, I really liked the Kevin Spacey one.
If you like that kind of intimate "actor's talk about their lives" interview process, you should check out Kevin Pollak's Chat Show. There have been a few really good interviews on there. Only thing you have to put up with is Kevin Pollak going off on the occasional tangent. And by occasional I mean all the freaking time.

It started as a podcast, but you can find videos of every video they've done on Youtube. They're usually about an hour and a half long, and they are really interesting.
