No Hard Feelings

From Newsday:

The roughly 10-week filming schedule “was all shot on Long Island,” according to location manager Josh Dorn.

Filming began in September 2022, according to Dorn, and included roughly one week in Montauk.

Salivar’s Clam & Chowder House, a family-owned fixture known for its rooftop deck, stood in for the restaurant where Lawrence’s character works part-time as a bartender.

A house on Startop Drive served as the exterior for the home of Percy’s parents, played by Matthew Broderick and Laura Benanti (the interior of the home was filmed in Locust Valley).

The famous Montauk Point Lighthouse serves as the backdrop for a “date” between Maddie and Percy,

and some filming took place at Gosman’s Dock as well.

“We did a bunch of driving shots and establishing shots all through the docks area,” Dorn said, “to show the world that Maddie lives in.”

Other parts of Long Island wound up playing the East End — a common practice that cuts down on travel expenses and hotel-room costs for the film crew, according to Dorn.

Ted’s Fishing Station, a well-known dock in Point Lookout, was relabeled “Montauk Dock East.”

An action-filled scene featuring Maddie clinging to the hood of a moving car driven by Percy, was filmed at The Sands, the private beach club in Atlantic Beach.

Other shooting locations included Oyster Bay,

Lawrence and

Greenfield Cemetery in Uniondale (though the graveside scene with Maddie was eventually cut from the film).

“We kind of faked Montauk all through Nassau County,” Dorn said.
