William H Macy has confessed he does sometimes feel shamed by the plots and lines in hit show Shameless.
The Fargo star plays drunken freeloader Frank Gallagher in the US version of the award-winning Channel 4 comedy drama, co-starring Emmy Rossum as his eldest daughter.
William revealed: "Once or twice I've said, 'Too much. Too despicable. It's over the line.'
"But it's the writers' job to push that line, to put every character in really uncomfortable situations. So we have a good, healthy tug of war."
He added: "I pride myself on taking the script and saying, 'I can DO this!' I take all the stuff the writers can shovel my way!"
While the Sessions star says, "I flatter myself that, as an actor, I do a pretty good drunk", he also admitted his wardrobe helps him get into character as scruffy Frank. He confessed he has almost never changed his costume.
"I wear the same clothes almost all the time," he revealed.
"And I pride myself on this, as does our costumer, Lyn [Paolo]: I've never had a fitting. She has sent me pants with the top two buttons missing and the waist too big. So I put a belt on it, I fix it. With Frank, close is good enough."
William, 62, has been nominated for an Oscar for his film work, but he confessed after seeing his wife, Felicity Huffman, starring in hit show Desperate Housewives: "I was jealous. I said, 'I want to do TV, too!'."
