Colin Farrell, 45, shows off his buff physique while out for a shirtless run in Los Angeles

Colin Farrell was spotted keeping up his impressive physique on Saturday when he went for a jog in Los Angeles.

The 45-year-old actor showed off his abs and toned arms while catching some sun during a shirtless run.

He kept the rest of his minimal look sporty with black athletic shorts and black polka dot socks, plus gray-and-red trainers.

Colin sported a close-cropped goatee and had his spiky salt-and-pepper hair held back with a dark blue headband.

He was back on the West Coast after traveling to Australia earlier this month while filming Ron Howard’s upcoming drama Thirteen Lives.

He stars in the film, which also features Viggo Mortenson and Joel Edgerton, as the British cave diver John Volanthen, who was instrumental in helping to rescue a Thai junior soccer team and their coach after they became trapped in a cave when rising waters from rains flooded it and blocked their exit.

All 13 trapped people were eventually rescued, though two divers lost their lives as a result of the rescue.

Earlier this month, it was announced that Colin would be reuniting with Rachel Weisz, his costar in the dark romantic comedy The Lobster, for another dark comedy titled Love Child.

The Oedipal film, directed by Storytelling’s Todd Solondz, concerns a precocious child who schemes to get rid of his oafish father so that he can keep his mother, until an attractive stranger arrives and shakes up his plans.

‘This is my first movie with a plot and my first movie taking place in Texas. It’s fun and it’s sexy and it’s shaped by the Hollywood movies that made me want to become a filmmaker,’ Solondz said in a statement. ‘I’ve loved Rachel and Colin’s work forever, and am so honored to be able to excite their passion for serious and unexpected work as well.’

The Irish actor also has some bigger budget fare heading to theaters next year.

He looks nearly unrecognizable in early images from The Batman, a reboot of the series which stars Robert Pattinson as a younger version of the Caped Crusader.

Colin plays one of the film’s multiple antagonists, Oswald Cobblepot, better known as the Penguin.

Fans may not even recognize him in the part, as he wore extensive facial prosthetics and also gained some weight for the part, though he seems to have already worked it off.

Zoë Kravitz is also featured as Batman’s foe/romantic interest Catwoman, while Paul Dano stars as a darker update on The Riddler, who is now a serial killer.

The highly anticipated comic book thriller is set for a March 2022 release.
