Colin Farrell is unrecognizable behind his extensive facial prosthetics as he films a scene for his Batman spinoff series The Penguin in New York City

Colin Farrell was back at work on the set of his upcoming Batman spinoff series The Penguin on Tuesday.

The 46-year-old Irish actor was covered up by layers of prosthetics to help him achieve the look of Oswald ‘Oz’ Cobblepot, better known as The Penguin.

He is taking a standalone series about the comic crime figure to HBO Max, even as the service has canceled some of its other DC Comics shows.

Farrell appeared to be filming a crowd scene on Tuesday, and he was seen followed by a bevy of other actors.

The actor — who recently lost out on the Best Actor Oscar to Brendan Fraser — was costumed in a classy single-button plaid charcoal suit.

What a difference! By contrast, Farrell was spotted earlier in the day in casual clothes and with his short dark hair spiked up

He wore a short black tie with the look and covered up with a cool-looking black leather overcoat with wide lapels.

He channeled classic Hollywood gangsters with a pair of shiny black leather shoes with charcoal spats.

Earlier in the day, Colin was seen without his prosthetics on set. He kept things casual with a gray V-neck T-shirt and navy sweatpants, along with black-and-white Adidas slide sandals.

The Lobster star wore his short dark hair swept up in spikes, but it appeared to have been completely covered up once he sat through hours of prosthetic work.

Colin’s thick head of hair was replaced by a balding pate with thin strands of receding hair swept back.

The new look completely swallowed up his natural features, which were replaced by a more hooked nose, several deep facial scars and a doughier chin.

He also appeared to have padding on his body that was hidden by his suit, which gave him a more heavyset appearance, though his version of The Penguin is slimmer than some past portrayals and illustrations of the character in many Batman comics.

Colin’s true identity was likely unknown to many people who saw him in the critically acclaimed blockbuster The Batman, in which he starred opposite Robert Pattinson, who played a younger, more inexperienced version of the title hero.

The prosthetics didn’t appear to stop him from doing any of his usual activities, and he was spotted taking a puff from a red vape device during some downtime at the top of a set of steps.

He removed his suit jacket and overcoat to help cool down.

Back in January, Colin admitted while being honored at the Palm Springs International Film Festival that he had no idea his supporting role in The Batman would launch its own series.

‘The only thing I had an idea was that I wasn’t nearly getting to explore the character as much as I wanted to,’ he admitted to Variety.

‘Because there was all this extraordinary work done by [makeup artists] Mike Marino and Mike Fontaine and his team, and I just thought it was the tip of the iceberg, pardon the pun, that we were getting to do the six or seven scenes that we did in the film. I was grateful for them, but I wanted more,’ he said.

In fact, Penguin wasn’t even the primary antagonist of the film, as that role belonged to a chilling serial killer version of the Riddler — played by Paul Dano — which was inspired by depictions of the never-caught Zodiac killer.

Colin noted that part of why he wanted to pursue a spinoff series was due to Mike Marino’s prosthetic work.

He joked at the time that he was able to go to a Starbucks without being mobbed by gawkers the first time that he put on the prosthetics, before adding that crowds are more respectful when he’s back home in Ireland.

‘They’re cool about it in Ireland. People don’t be looking,’ he said. ‘People don’t be paying as much attention as you think!’

Colin was previously seen on Wednesday of last week as he filmed a scene with his costar Rhenzy Felix.

Transformed: The new look completely swallowed up his natural features, which were replaced by a more hooked nose, several deep facial scars and a doughier chin

Taking a puff: He was still able to do everyday activities with the prosthetics, including taking a hit from a red vape device

More stories to tell: In January, Colin admitted to Variety at the Palm Springs International Film Festival that he wanted to do the Penguin miniseries because he was disappointed that he didn’t get to explore the character more in The Batman

Keeping it under wraps: So far, a release date for The Penguin has not been announced

Plot details about Colin’s eight-episode miniseries are being kept under wraps, but it is believed to take place immediately after the events of The Batman.

In that film, he worked as a top lieutenant for the crime boss Carmine Falcone (John Turturro), but he was positioned to take over the top spot of his crime family by the end of the film.

Notably, Penguin appeared to be attending a funeral, based on the all-black outfits of the other actors gathered around him and vases of red roses lining the stairs.

So far, a release date for The Penguin has not been announced.
