Honestly, the first time I saw a photo of Oswald "Oz" Cobb from the 2022 film The Batman, I didn't believe it was him. You've probably had that same double-take. It wasn't just a "good" makeup job; it was a total erasure of one of the most recognizable faces in Hollywood. Colin Farrell penguin makeup has become a benchmark for what is possible in modern practical effects, and as the 2024 HBO series The Penguin proved, the magic trick only got more impressive with time.
Mike Marino is the name you need to know here. He’s the prosthetics designer behind the curtain. He didn't just give Farrell a fake nose and call it a day. He basically rebuilt a human being from the skin up.
The Man Behind the Mask
Mike Marino and his team at Prosthetic Renaissance didn't start with the intention of making Colin Farrell look like a comic book caricature. In fact, they drew inspiration from some pretty heavy places. Think Fredo Corleone from The Godfather. They wanted someone who looked like he’d survived a lifetime of Gotham’s worst nights—someone sweaty, slightly sickly, and perpetually on the verge of a breakdown.
Marino used platinum silicone (specifically PlatSil Gel-25) to create the pieces. This stuff is expensive and finicky, but it moves like real flesh. If you watch the show closely, you can see the way the "skin" on Oz’s neck folds when he turns his head. That’s not CGI. That’s just incredibly soft silicone glued to a very patient Irishman.
The application process was a marathon.
Every morning, Farrell would sit in the chair for about three hours. He’s gone on record saying he’d just drink black coffee and blast '80s music to get through it. There was a team of about five or six people—the "Team Penguin" crew—gluing, painting, and blending.

What went into the kit:
- A multi-piece facial prosthetic: This included the nose, cheeks, chin, and neck.
- A bald cap and toupee: Farrell has a legendary head of hair, which is actually a problem for makeup artists. For the movie, he shaved it. For the series, he didn't want to do that again, so they had to wrap his "massive" hair (Marino's words) tight to his scalp.
- Body suit: It wasn't just the face. Farrell wore a full body suit to give him the specific bulk and gait of the character.
- Dental pieces: To subtly change the shape of his mouth and the way he spoke.
Why the TV Show Was a "Nightmare" for the Artists
In a movie, you can hide a lot in the shadows. Matt Reeves’ The Batman was famously dark. If a seam on a prosthetic started to lift, or if the paint rubbed off on a collar, you might never notice in the dim light of a rainy Gotham street.
Television is different.
The HBO series put Oz in broad daylight, in high-definition, and in extreme close-ups for eight hours of content. Marino mentioned in interviews that the show was "harder on every level." They had to reinvent the makeup to be more refined because the camera was going to be inches from Farrell's face for months on end.
Then there was the heat.
Silicone doesn't breathe. When you're under studio lights for 14 hours, you sweat. That sweat creates air bubbles under the prosthetics. If those bubbles pop, the makeup "melts" or looks like it’s rotting. To stop this, production actually built a specialized "cooling tent" for Farrell. He called it the Igloo. It was basically a refrigerated room where he’d sit between takes to keep his core temperature down so his face wouldn't literally slide off.
The Skin Toll
Working 16-to-18-hour days in that much glue is brutal. Farrell has mentioned that the production actually couldn't work him two days in a row sometimes because his skin was breaking out so badly under the silicone. It’s the side of "movie magic" people don't usually talk about—the literal physical toll of being a canvas.
The result, though, was a 2025 Golden Globe for Best Actor in a Limited Series. When Farrell took the stage to accept, he joked, "I guess it’s prosthetics from here on out." It’s a funny line, but there’s truth to it. The makeup allowed him to disappear so completely that he could make choices he might not have made with his own face. It’s a psychological shield.
What Most People Miss About the Design
Look at the eyebrows. Marino didn't just make them bushy; he looked at actual penguins. The angles of the prosthetic brow mimic the sharp, aggressive lines of a bird’s facial structure. There’s even tiny bits of white hair mixed into the brows to give that "black-and-white" contrast, a subtle nod to the character's namesake.
Also, the scars. They aren't random. Every "tuck mark" and pockmark on Oz's face was designed to tell a story of a guy who has been in a lot of back-alley fights. It gives him a "hyper-realistic" texture that makes you forget you're looking at a movie star.
If you’re a filmmaker or just a fan of the craft, the big takeaway from the Colin Farrell penguin makeup is that practical effects are far from dead. In an era where "we'll fix it in post" is the default, this transformation proved that having something real on set—something the actor can feel and the camera can actually see—is still the gold standard for immersion.
To really appreciate the work, watch the scenes in The Penguin where Oz is in the bathtub or partially clothed. The way the makeup team transitioned the facial prosthetics into the body suit is a masterclass in blending. You can't see the seams because, quite frankly, they didn't leave any.
