I stumbled on to this internet talk show while reading the blog section on the Mad Men website. (Season 3 starting in August!) Kevin Pollack is a character actor who's been around for a long time, and while I'm certain I've seen dozens of movies starring him, I fail to name any off the top of my head. He's sort of a cross between Kevin Spacey and Paul Giamatti, and I bet I used to confuse him with Giamatti all the time, before Sideways came out and made Giamatti a household name.
(Can you tell which one he is?)
