“That was another thing where literally I got a call on a Wednesday and my manager said, ‘Look, you’re Irish. How’s your Irish accent?’ I said, ‘I don’t know. I haven’t had to do one for years. Why?’ ‘Well, there’s this great role. You’ve been offered this great role on Sons of Anarchy playing this guy Jimmy O’Phelan, but he’s Irish. He’s from Belfast.’ And I went, ‘Oh, Jesus. Okay.’”

The one caveat? The role was shooting in a few days’ time. Titus Welliver recalls doing as much prep as possible, which included calling a few cousins in Ireland and just listening to them talk, before he shot the part. “I had to kind of make it up as I went along, to be honest with you,” he adds, chuckling as he notes that his son found someone online saying that his portrayal involves “the worst Irish accent ever.”
