He told Closer US: "Mutual respect and patience, I always feel like a successful marriage is one that has an equal number of apologies on both sides. People have to be willing to be humble, be forgiving, and be apologetic and not hold on to slights. I'm so fortunate, she's the right life partner for me."

He said: "I have two daughters and two grandchildren. As I said, I also have nine siblings, so family keeps me pretty busy. I also like to read. I try to keep a good balance between my work and my personal life.
"[Being a grandparent] is fantastic. You get to spoil them and then hand them back when it gets to be exhausting. But they're the light of our lives."
The 'Monk' star began his career on the stage more than 40 years ago and Tony for his role in in the Broadway musical 'The Band's Visit' in 2017 and admitted that he would love to tread the boards again whenever possible.

"But I think when you have good material and you're working with people you admire and respect, that's all that matters."
