A lot of the same actors were in both shows. Anthony Denison I like him because he had a dead facial expression if you know what I mean when he did violence, the guy who played Paulie they say he was a real thief when they found him for the part.dennis farina who played torello was a real Chicago cop before he became an actor.
So many good actors were on both shows one was keven spacey, Julia Roberts when she was very young.
