Jessica Alba holds an unusual spot for an actor.

A showbiz veteran at 43, she is also, from her side job starting a company that distributed diapers, a billionaire.

“Trigger Warning,” which streams globally on Netflix Friday, marks a return to her action-packed roots.

As Parker, Alba is ex-Special Forces. She returns to her hometown following the sudden death of her father and inherits his bar. All too soon, as a gang seizes control, Parker goes from stealth attacks until a showdown becomes inevitable.

“Trigger” has been in development for years. Only when Alba stepped down from running her Honest Company to take a seat on the board, did production proceed.

“It was a bit of a process because it was so far from what you see on screen today,” she began in a Zoom interview. “This genre is pretty male dominant and a lot of times you see characters that are a male fantasy version of a woman, which doesn’t feel very relatable to women.

“I wanted a really gritty, raw, cool action movie that was like a throwback action movie. But one where women can be totally like Parker.  I love Parker, I can see myself in Parker.

“My feeling is she’s my friend or my neighbor. My sister.”

As executive producer Alba saw the script rewritten by a woman and hired Indonesian director Mouly Surya in her English language debut.

“Rather quickly, we pulled back a lot of the scenes that just felt unnecessary, weird or didn’t sit right,” she said. “We really wanted to lean more into the development of her motivation.

“Like, Why is she here? What is this movie really about? What is she fighting for?

“We’re creating how she would be this hero who comes out of nowhere. The men in this town never saw her coming. She can essentially fight for what’s right. And the good can, in the end, win. That’s always a hopeful story where a good guy can win.”

Alba knew “Trigger’ depended on her making it real.

“I started my career, really in this action genre, with a TV show called ‘Dark Angel’” – 2011 to ’15 – “and I trained for nearly two years before we even started shooting that show.

“So I got to take a lot of that foundation and that skill set and apply it to this movie.

“But I’d never done knife training and I got to learn how to fight with a knife. For me that made the hand to hand combat more realistic.

“That I could take out a big dude if I had a knife in hand, immobilize him with the knife as I was fighting.”
