In a gossipy article on Death and Taxes (http://www.deathandtaxesmag.com/204250/11-actors-everyone-hates-to-work-with/?-0) about actors no one likes to work with, all the other stories were rumors from others, but MP said this about himself.
“Homeland” actor Mandy Patinkin admitted to New York Times Magazine that, on the medical TV drama “Chicago Hope,” he was too big for his scrubby pants. “I struggled with letting in other people’s opinions,” he said. “I never let directors talk to me, because I was so spoiled. I started off with people like 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.”
