Jeremy Renner is giving fans a taste of what's to come on "Mayor of Kingstown."
The actor joined "Good Morning America" on Tuesday morning to give a sneak peek at the upcoming fourth season of his thriller series.
Renner also touched on his second season returning to work after his 2023 snowplow accident and his work with foster care children.
"Edie Falco I think is a really great highlight," Renner said of the upcoming season, calling his co-star's character, a prison warden, a "great adversary."
"She creates a lot of problems for me to get to try to protect my brother, who's a cop who goes to prison. So there's a lot of a lot of tension that goes on between us two," he continued, adding of Falco, "She's tremendous."
Renner said he and Falco had to make time outside of filming to really get to know each other.
"I've never met her, so we kind of met in character almost. And so, we'd always, whenever we stopped acting, we try to like catch up," he said, adding that because her character can be intense, he wanted to be able to remind himself that "she's a nice person, right?"
Describing the narrative layout of season 4, Renner said, "There's only really one main story that threads all the main characters into this main story, [which is] my brother being incarcerated."
The upcoming fourth season of the drama, which focuses on the underbelly of the prison system through the McLusky family, releases Oct. 26.
Renner also spoke Tuesday about what it was like filming his second season of the show after his 2023 accident, in which he was crushed by a 7-ton snowplow on New Year's Day.
The accident left Renner with more than 30 broken bones and led to months of recovery.
"Season three was very difficult for me, because I just had to focus on getting better. And a lot of people helped me to get better while I was working this," he said, reflecting on the previous season of the show.
He said filming season 4 was "much more, I guess, fun in the sense of I can have a personality and kind of talk with people and not just worry about my next step."
He said he was able to focus more on his role as an executive producer this season.
The actor also spoke about his work with foster care children via his organization, the RennerVation Foundation. He described working with the Department of Children and Family Services in Los Angeles County with his sister, providing assistance to kids who are aging out of the foster care system.
"It's, like, 400,000 kids across our country that are just marginalized and pushed to the side, and it's very upsetting to me. So I, instead of getting upset about it, do something about it and try to provide some assistance and hope and love for these kids that so deserve it," he said.
