Shark Tank star Kevin O’Leary has made his acting debut in the upcoming 2025 sports comedy-drama “Marty Supreme,” despite friends and advisors warning him not to “take this role.”
From boardroom to big screen
O’Leary, known for his sharp business instincts on Shark Tank, has entered Hollywood by playing Milton Rockwella wealthy and aggressive businessman in the 1952 film Marty Supreme.
“So when I was offered this role, a lot of people around me – consultants, agents, whatever – said, ‘Don’t do this… You don’t know how to act,’” O’Leary recalled in an interview on CNBC this week.
Despite the warnings, O’Leary accepted the role, attracted by the character’s alignment with his own no-nonsense personality.
Josh Safdie called and said they were writing Marty Supreme and there was a character named Milton Rockwell – the richest man in America, 1952, and “a total A-hole,” the investor recalled, saying it was “perfect.”

Marty Supreme World is set in the 1950s
O’Leary described how the film’s authentic set design, period wardrobe and props helped him get into character.
On the first day he completed seven pages Timothée Chalamet And Gwyneth Paltrow. The watches, the clothes, the surroundings — they all scream 1952, O’Leary said, adding that after a few takes, “the cadence of the scene” took over and he was even able to improvise.
Working with Chalamet, who shines as Marty Mauseran aspiring ping pong champion, was particularly inspiring, the Shark Tank star said.
“Sparks fly from that guy. He’s great and suddenly you’re in it and you don’t even know your reading lines anymore, and that’s the magic,” O’Leary said.
