For Carla Gugino “The Girls on the Bus” marks a turning point in a career that began in her early teens.

The 10-episode MAX series follows four women covering a national political campaign. Among them, Gugino’s veteran reporter Grace Gordon Greene is acknowledged as “Queen of the Scoop.”

“Girls on the Bus” is based on “Chasing Hillary,” Amy Chosick’s 2018 nonfiction book about covering Hillary Clinton’s 2016 presidential campaign.

“This is a story,” Gugino explained in a Zoom interview, “about four women who are from different backgrounds, different generations, different political beliefs, different ideologies, who find themselves thrust together on this adventure in very close quarters.

“Ultimately, they have to figure out how to do it together. How to put themselves in the other person’s shoes and realize that ultimately supporting someone in a belief that might be different than yours is not sacrificing your beliefs. It’s actually just putting human connection first.

“All of those themes are things that I really believe in.”

She also realized, “That I’m at the point in my career in which I’m the ‘seasoned older’ veteran.”

Gugino, 52, laughed.  “Yes, I’m where you’ve got to wake up to these realities.”

But her Grace is neither bitter, caustic or nasty. Grace’s positive attitude was essential for this veteran whose career began in her early teens.

“Yes, Grace has been there and done that. But really key to me is that she’s remained curious,” Gugino.  “Curious and incredibly passionate. Journalism — and certainly in political journalism — is an unpopular profession. In the sense that much like a detective you’re finding out information about people that they may not want you to know. And your job is to, as accurately and quickly as possible, get that information to the public.

“That takes a certain kind of personality. It takes a pretty tough skin. And Grace has that. But it was very key to me that she also has an incredibly generous heart.

“She ultimately is there to help these younger women find their path. For me, that’s something as a young actor that I really appreciated from those that I got to work with.

“I really noticed the ones I got that from — and those I didn’t. And I knew that I never wanted to be that kind of person who didn’t try to help.

“I always wanted to be there to help usher people into a new world.”

She continues to discover new worlds from her roles. “The most interesting aspect of ‘Girls on the Bus’ wasn’t about me. It was more the mechanics and lifestyle of what it is to be on the road as a journalist in a political campaign.”

MAX streams the first 2 episodes of 10 of “The Girls on the Bus” on March 14.
