In TV series “Jett,” out Friday, Carla Gugino plays a badass. What that part of her looks like I don’t know — but the rest of her’s great. Waist the size of a swollen kneecap. Eyelashes thicker than Mexico’s someday wall. Gorgeous.

Carla: “In this, I play a thief who doesn’t care what people think of her. I’m someone who has skills. My character’s practical. Does whatever’s got to be done to get a job done. She screws up. Goes to prison for five years. Comes out. Figures she has to live a straight life.

“She has no maternal instincts. Think sort of a young tough female Clint Eastwood.

“She then gets hired, but it leads to connecting with more ruthless criminals, and she ends up with an old flame. In bed. And there’s a long love scene.”

I figure no reason to gloss over that quickly, so I ask what’s it like going nude.

“First, there’s good lighting. No side light. Body makeup. I’ve been lucky because you have to trust the director. You talk about what shots they’re taking. Sure, you feel vulnerable. But you know the other person is also compromising. Also nervous.

“In one scene in Havana, my character plays homage to the movie star Ava Gardner.”

And Carla’s off-screen life?

“I just visited my dad in Florida. He’s 90. And right out of the hospital, so I brought him healing crystals. He’s my inspiration. Sunday’s Father’s Day, but I leave tomorrow for Berlin. It’s a full-out action movie with Angela Bassett and Michelle Yeoh called ‘Gunpowder Milkshake.’ ”

Full-out action movie? Nude love scenes? She’s the one who needs healing crystals.
