Homeland star Mandy Patinkin has publicly apologised to his former Tv directors for acting "spoiled" and "abominably" on dramas like Chicago Hope and Criminal Minds.
In a recent New York Times Magazine profile, the veteran star admits he regrets his past behaviour and the way he treated Tv bosses.
He says, "I struggled with letting in other people's opinions. During Chicago Hope, I never let directors talk to me, because I was so spoiled. I started off with people like (directors) Milos Forman, Sidney Lumet, James Lapine - unbelievably gifted people - so there I was saying, 'Don't talk to me, I don't want your opinion'.
"I behaved abominably. I don't care if my work was good or if I got an award for it. I'm not proud of how I was then, and it pained me."
And opening up about his departure from Tv drama Criminal Minds after two seasons, Patinkin tells the publication he made a mistake in signing up.
He adds, "It wasn't the right fit. I made a choice I didn't want to make. I pushed myself, thinking I needed more fame, more economic security. When Criminal Minds came along, I had just survived the discovery that I had prostate cancer, so I guess I had that vulnerability.
"I'll never forget sitting on the bed in my cousin's house in L.A. reading the first script, and I schmoozed myself, I brainwashed myself... I didn't listen to any piece of myself and I paid the price. I never expected to work in television again."
Talking about his new Tv hit, he states, "One of the greatest gifts that Homeland has given me is it's affirming on a daily basis. I'm always with the script, walking around with this stuff 24/7, so my head's in a good place. The role is about listening, and when you don't listen to yourself, you get in trouble."
