If there is indeed a zone, then Nick Offerman seems to be living in it these days.
I love stories about artists who succeed later in their career, and I think in Offerman's case, one of the reasons that Ron Swanson clicked is because there was a sense of authority that Offerman gives off that might not have been there in the same way if he was fifteen years younger. I look at him in something like "Sin City," and I can't imagine that guy as the same person who is giving one of the most amazing comedy performances on TV every single week right now.
I wrote about his new concert film on Valentine's Day this year, and the other night on the red carpet, when I heard him use the word "delicious" during an answer, it made me smile. He has this enormous zest for the life he's living right now, and a big part of that is his blatantly passionate relationship with his wife, actress Megan Mullally. He is certainly not shy about discussing just how passionate, either.
