"It's definitely taking a little bit of a darker twist," Winters told UPI of the blood feud between Tommy and Johnny. "As an actor, I tend to enjoy going to the dark side. I guess that's due to my six-year stint on (the HBO prison drama) 'Oz.' But I am enjoying the arc this season and Denis has found a rhythm, which is captivating."
Last week's episode ended with Tommy thrashing Johnny at a family birthday party.
"It's the longest scene I ever had to shoot," Winters said, noting he did 80 percent of the stunts himself. "A few bruises came out of that one."
Asked if the expanded role was worth it, Winters quipped: "It seems my theme this season is suffering. ... It's always good to mix it up. Don't get me wrong, I'm having a great time."
