I'll butt in...yes, it's stars the brilliant Michael Chiklis who is astonishing in the role of Vic Mackey. See the post below your last one.
Though to be perfectly honest, I haven't seen him perform too many dramatic roles.
When Michael Chiklis starred as John Belushi in the movie version of Bob Woodward's unflattering biography Wired, he was dumped on by SNL cast members, some of whom suggested he wouldn't work in Hollywood after trashing the memory of Belushi. Primary among these were Dan Aykroyd.
Who's not working now?
I saw him on a talkshow recently, and it was funny to see what he's really like compared to his character. While Mackey is a very gritty, believable hardass, Chiklis himself is a jolly, easygoing kidder. It's always fascinating to see how well a good actor can assume a completely different personality onscreen and make it 100% convincing.
Similarly, Harrison Ford comes across in interviews as an aging "surfer dude", is rather soft-spoken (and his speaking voice is at least half an octave higher than his "acting" voice), and usually has a goofy grin on his face, whereas in most roles he's a very "manly man", strong and assertive.
