McBride and I talked a lot about masculinity, about fathers and sons. It is a central theme of “Gemstones” — and the Bible, he noted — with its “Succession”-like story about a powerful megachurch pastor (John Goodman) and his three feckless children. (Adam Devine plays the younger brother, Kelvin.) McBride’s own father left when he was young, and he hasn’t seen him since high school. But he insisted he isn’t resentful.

“I like how my life turned out,” said McBride, himself a father of two. “Him exiting from our life is probably part of what enabled me to be able to go on and do the things that I did.” The biggest effect it had on his life, he said, was to make him more determined to be a supportive parent.

McBride loves his characters and the South in the complex, sometimes ruthless way of familial love. On the surface, “Gemstones” picks some easy marks — megachurches, new money, homoerotic jocks; Season 3 promises monster trucks and militias — but soft targets can be tougher to nail. What allows for authenticity is affection, however complicated.

“That’s the tightrope,” he said. “A lot of times I see, when things in the South are presented, it’s always such a boring take.”

Back on Day 1, after we all spilled out of the party bus, we wound up on a muddy oyster skiff off Wadmalaw Island, several shots down, pulling salty Sea Cloud oysters straight from their floating cages. Still, having only just met McBride, it was hard not to wonder how much of the day’s events were a show put on for the benefit of a reporter — a good-time performance by a performer who plays characters who are constantly performing.

I asked everyone I talked to about him afterward; they all insisted I shouldn’t flatter myself.

“I want you to feel really special right now, but that’s kind of Danny,” said Cassidy Freeman, who plays Jesse’s beleaguered wife, Amber. When McBride is the ringmaster, “everyone’s invited,” she added. Hill called him “the fun coordinator of our group.”
