As Season 4 of “Godfather of Harlem” returns Sunday, so do the legendary mobsters and molls of the MGM+ series with their reliance on murder, mayhem and drug dealing.

Two of the series’ stars, Lucy Fry and Michael Raymond James, discussed where their characters’ currently stand and how they’ve evolved.

“As Joe Colombo at the end of last season, I was sent off to prison,” James, 47, said of the high-profile crime boss of one of the era’s five ruling mafia families. “We catch up with him 18 months later as he’s just gotten released. He’s in a bit of a bad mood about it.

“Which is only fair. So, Joe comes in with a lot of hostility, a lot of anger, a lot of rage for what happened. He’s up to settle some scores and honestly, it only builds from there. I mean, it gets pretty intense this year.”

Lucy Fry, 33, returns as Stella Gigante, the ambitious daughter of Vincent D’Onofrio’s Genovese crime family boss Vincent “The Chin” Gigante.

“Throughout Season 3 she was working with Joe Colombo. Now she’s decided she wants to stay in New York and claim power for herself. Working with the mafia instead of trying to escape it and her father, like she had in previous seasons.

“She’s coming in now with the drive to claim power for herself within that world.”

The “Godfather of Harlem” is Forest Whitaker’s Bumpy Johnson, a real-life figure who, since this Chris Brancato (“Narcos,” “Narcos: Mexico”) series began, struggles to wrest control from the Genovese mob.

“This isn’t a documentary. There’s elements of history that we acknowledge, and other things where we take a liberal amount of dramatic license,” James said.

At one point Fry notes, “It’s 1966. I’m a woman in this organization.”

“She’s trying to get her dad to realize that he needs to progress with the times. Things are changing. As a woman, she can be working in the mafia and take that power for herself.

“Which isn’t necessarily historically accurate,” Fry allowed. “That is creative license to allow Stella to grow into a position of power.

“But to some extent at that time, that was happening. It’s not totally wrong to say that. To tell her father to get with the times and to give her more trust and respect as a career woman.

“Essentially, she’s trying to build her life and make this into a job. She’s trying to tell her father a woman’s place isn’t just in the kitchen or to be married and have children.”
