The show must go on, as they say!

On Tuesday night, New York City billionaire John Catsimatidis held a special screening of “Marty Supreme,” inviting an array of political figures to join him in celebrating his small role in the movie, which is already generating Oscar buzz.

However, shortly after the Timothée Chalamet film kicked off, an audio issue arose, leading to an unexpected 40-minute delay at the AMC Kips Bay 15 event.

Despite the setback, the Gristedes supermarket tycoon and former mayoral hopeful turned the situation in his favor.

“He got 40 minutes of one-on-one time with the governor,” noted a source, highlighting that the WABC radio station owner was seated next to Governor Kathy Hochul—who remained unfazed by the prolonged technical hiccup.

A pic showed the pair happily chomping on popcorn.

Adding some political intrigue to the scene, GOP gubernatorial hopeful Bruce Blakeman also attended the screening — marking the first time he and Hochul were in the same place at the same time since he announced.

Meanwhile, Mayor Eric Adams was supposed to be on hand to declare it Catsimatidis Day in NYC — but the tech snafu scuttled the plan to make the proclamation inside the theater.

Mayor-elect Zohran Mamdani previously attended the film’s NYC premiere.

Catsimatidis, 77, has a cameo in the movie, an awards front-runner. He told The Post last summer of the role: “I actually got paid! I’m a member of SAG. And so I got a new career at my age.”

(Buzz is that he’s actually quite good in his acting debut.)

In fact, Cats has now gotten the Hollywood bug. Said a source of his cameo, “John loved it so much, he’s looking to buy a movie studio. He’s talking to people.”

But don’t expect any dark horse bids for Warner Bros. The source said the mogul wants to build studio space “out East” on Long Island. “He’s thinking about doing something,” they said, adding Cats was talking at the event to NYC’s film and TV commish. “It’s John’s next chapter.”

It was proclaimed Catsimatidis day in NYC as well as two Long Island counties.
