Nick Offerman has a strong work ethic. When he signed up to play former pro wrestler James “Jinx” Millet in “Margo’s Got Money Troubles,” he worried he’d have to train as hard as other Hollywood gym rats.

“I’ve seen Mark Wahlberg’s social media,” he says. He thought, “I guess I have to get up at three in the morning?” but was very happy to learn that was “entirely unnecessary” for this part.

While Offerman did work with a trainer to get in fighting shape, it was much more manageable for a series that showcases his emotional strength as much as brawn. In the offbeat family story, Jinx is a newly clean addict who reenters the life of his estranged daughter Margo (Elle Fanning) once she gets pregnant.

Offerman says he was attracted to many elements of the show: Working with creator and showrunner David E. Kelley, producers and actresses Michelle Pfeiffer and Nicole Kidman, and Rufi Thorpe’s novel of the same name, which served as the source material. But chief among them was the opportunity to collaborate with Fanning, whom Offerman and his wife, Megan Mullally, admired while watching her series “The Great.”
