Joe Mantegna is about as Chicago as they come. He grew up in Chicago, he talks like he’s from Chicago, he got his acting start in Chicago, he even used to play with the band Chicago. That might explain why he tells Marc he still thinks of himself as a blue collar guy with a blue collar job. Joe talks about the moment West Side Story changed his life, how David Mamet became his champion, and why he choses such a wide variety of projects, including his 13 years on Criminal Minds and his 30 years as Fat Tony on The Simpsons. This episode is sponsored by Stamps.com and Shyn.
