Julia Roberts' Netflix movie 'Leave the World Behind' filming on Long Island

Rumaan Alam's acclaimed novel "Leave the World Behind," set in the Hamptons, is being filmed on locations around Long Island for a Netflix movie starring Julia Roberts, Ethan Hawke and Mahershala Ali.

On Monday and Tuesday, filming took place in the Lloyd Neck section of the Village of Lloyd Harbor, both at the Caumsett State Historic Park Preserve, where what appeared to be parts of an airplane-fuselage prop could be seen on the beach, and on private property in the vicinity of Beach Drive and Soundview Drive North.

"As usual, the Lloyd Harbor Police Department was available for crowd control and traffic situations," said Village Clerk Jill Cervini. The Fox investigative drama "Prodigal Son" had shot at the Marshall Field III Main House in Caumsett Park in March 2021.

"Leave the World Behind," written and directed by Emmy-nominated "Mr. Robot" creator Sam Esmail, adapts Alam's 2020 novel about New York City couple Amanda and Clay, who with their teenage son and daughter are vacationing for a week in an Airbnb home in a remote part of Long Island. Late one night, an older Black couple, Ruth and G. H., arrive in a panic, saying they are the home's owners and that a blackout has afflicted the city. With TV, internet and cell service all down in this rural enclave, Amanda and Clay have no idea whether to believe them — though ultimately, a more apocalyptic truth takes hold.

Denzel Washington initially had been set to star when the project was announced in July 2020, but by September 2021 he had been replaced by two-time Academy Award winner Ali.

Additionally, Riverhead Town Board at its meeting Tuesday   gave Netflix Productions permission to use several locations for film shoots during the week beginning April 25.

A Netflix representative told Newsday, "As a rule we don't confirm locations or dates during production."
