Netflix Debuts Gilgo Beach Killer Movie Filmed On North Fork

SOUTHOLD, NY — Netflix is set to debut a new movie filmed on the North Fork in 2018 about the Gilgo Beach murders, which rocked Long Island and led to the desperate search for a serial killer who has never been found.

According to imdb.com, "Lost Girls" is set to premiere Jan. 28 at the Sundance Film Festival and then be shown on Netflix.

The film is based on the book "Lost Girls: An Unsolved American Mystery" by Robert Kolker, according to producer Anne Carey.

When asked why Southold was chosen for the filming, Carey noted the beach. "It's a beautiful location, with a very cooperative community," she said. "It had the right creative elements."

A post in Broadwayworld.com said the film is "a true-crime story and a strong character piece" revolving around the agonizing search of one mother, Mari Gilbert, for her daughter Shannan, a sex worker who went missing in 2010 and who was later found murdered.

The film stars Amy Ryan of "The Office" and "Gone Baby Gone"; Miriam Shor of "Hedwig and the Angry Itch"; and Gabriel Byrne of "The Usual Suspects"; and is directed by Liz Garbus, the post said.

The search for Gilbert first led to the bodies of four other prostitutes, all of whom were strangled and stuffed in burlap bags. A total of 11 sets of human remains, including Gilbert's, were found along Ocean Parkway. Police have been searching for a serial killer ever since.

Mari Gilbert was later murdered by another daughter, police said.

According to a filming permit from Always Am Productions Inc. approved by Southold Town, the crew began work Oct. 26, 2018, at the Kenney's Beach parking lot and continued Oct. 29 with an actor "leading a march of women" to a gate; filming continued at a private home on Leeton Drive.

One day of shooting included an actor "leading a vigil" at the Kenney's Beach parking lot; on the next day, filming on Leeton Drive included a "girl running down" the street.

Filming also took place at the Mattituck Motel, according to the permit.
