To put it, well, bluntly – Patrick Stewart was born to play British journalist and TV personality Walter Blunt.

“I am obsessed with newspapers. My first job was working on one – politics and current affairs,” Stewart, 75, tells PEOPLE of his lead role in the new Starz comedy, Blunt Talk.

“I am fascinated by news anchors and presenters, how they can influence and inform opinion.”

And when it came time for Stewart to prepare for the part, he turned to some of his favorite anchors for “invaluable insights” into how they do their jobs.

“Through the generosity of Jon Stewart, Rachel Maddow and their respective production teams, I monitored The Daily Show and The Rachel Maddow Show from a fly-on-the-wall point of view,” Stewart says.

But just because Walter is a newsman doesn’t mean he’s at all uptight.

“Unfortunately his private life is chaotic and unpredictable, involving women he encounters, ex-wives, illegal substances, alcohol and classic cars,” Stewart says. “He also has two children by previous marriages and a ‘black book’ for when he feels lonely and discouraged.”

Still, Stewart feels Walter has a good heart.

“He believes he has a vision for America, a place he loves,” he says. “That vision often leads him into turbulent, treacherous waters, but he is a man of passion and strong convictions and determined to make the USA and the world a better place to live.”

Blunt Talk premieres Saturday, Aug. 22, at 9 p.m. (ET) on Starz.
