You would think a performing arts hall in Connecticut named after Katharine Hepburn, in a quiet seaside town like Old Saybrook would be safe. You would think a crowd of mostly ex-hippie gray-hairs, who had paid to sit in plush red chairs, hear you sing and have you sign their “Bad News Bears” posters, would be free of hecklers.

You would be wrong. And now Billy Bob Thornton, on tour with his rock band the Boxmasters, was going to have to invite a man who had just called him a “condescending jerk” — except he hadn’t shouted “jerk” — to come up and sit on the edge of the stage with him and work this out, man to man. He was going to have to explain, as he has surely gotten tired of explaining, that he isn’t who you think he is.

“I can tell you people that I know personally, who will walk by every fan and not even look at them,” he said from the stage. “I stand by the bus and I sign every person’s picture. I talk to everybody. I take a picture with everyone.”

It was, in the end, a perfectly pleasant conversation, but one might assume that at 69, a man of Thornton’s acclaim and accomplishments wouldn’t feel the need to plead his case at all. Again wrong. While he was reluctant to talk about the incident when we caught up by phone a few weeks later, he is otherwise open about his insecurities and his feelings of being misunderstood, just as he is open about his disappointments — particularly his disappointments with Hollywood.

If Thornton has appeared to pull back from Hollywood a bit in recent years, that is by design. The once up-and-coming filmmaker who wrote, directed and starred in the Oscar-winning “Sling Blade” had already given up writing and directing movies years ago because of how studios treated him just after that 1996 film — something he is “still pissed off” about, he said. He still loves acting but is increasingly selective: His role in the new Taylor Sheridan series “Landman,” premiering Sunday on Paramount+, is one of only a handful of major roles he has taken since “Bad Santa 2,” from 2016.
