Colin Farrell stunned onlookers with a newly shaved head while stepping out in Los Angeles.

The “Penguin” actor was pictured on a lunch outing on Wednesday, rocking a completely smooth head. He showed off his fit physique in an olive green T-shirt and casual black pants, and accessorized with a pair of sunglasses.

In another snapshot, the “Batman” actor, 50, covered the new look with a blue ball cap and finished it off with brown loafers.

Farrell appeared relaxed, carrying a cell phone as he navigated parking meters in the city.

It’s unclear why the “Minority Report” actor was sporting the tough new look — but in June, the actor shared he was beginning to film “The Batman Part II,” in which he’ll reprise his role as Oz Cobb, aka The Penguin.

“I’m so excited to see it as a fan,” Farrell told Collider at the time, adding that the script for the sequel is “extraordinary.”

“Matt is just so brilliant, and he just cares so deeply about the stories he tells,” he said, referencing the film’s director and co-writer, Matt Reeves.

The “In Bruges” actor famously made an astonishing transformation into the character for 2022’s “The Batman,” complete with scarred facial prosthetics and a partially bald pate, and again for the HBO spinoff series “The Penguin.”

Although he was highly celebrated for his turn as Oz Cobb in the 2024 spinoff series — even winning a 2025 Golden Globe — it’s unclear if the series will return for a second season.

The “Banshees of Inisherin” star’s look isn’t entirely new — in 2021, ahead of “The Batman’s” debut, Farrell was previously spotted stepping out in the Los Feliz neighborhood of Los Angeles with a completely shaved head.

At the 2024 red carpet premiere for “The Penguin,” the star opened up about seeing himself in the mirror after transforming into the ruthless crime boss.

“Do you ever see cats looking at themselves in the mirror? How they recoil and they just don’t know [it’s them]?” he told reporters at the event. “It was strange.”

Farrell clarified that he didn’t ever “fully” lose “sense of” himself, but noted that it “was a very powerful thing to know yourself a certain way for 45 years and to see a reflection.”  

“And it also kind of made me aware of how much I identified with how I look,” he continued. Farrell reflected on realizing that “none of” him was there and how it created a “blank slate” to fully become the character.

“It was amazing,” he divulged. “It was really, really powerful. It was something very powerful and very kind of hypnotic to the experience.”
