Lost Girls, Movie About Gilgo Murders, Debuts on Netflix in March

Netflix’ Lost Girls movie is based on the true crime book of the same name.

Lost Girls, a movie based on the nonfiction book of the same name chronicling the unsolved Long Island Serial Killer case, is set to be released on Netflix on March 13, the company announced Thursday.

Actress Amy Ryan will play Mari Gilbert, the mother of Shannan Gilbert, the missing woman Suffolk County police were searching for when they uncovered 10 sets of human remains in and around Gilgo Beach on Ocean Parkway.

The real-life Marie was murdered by Shannan’s sister, but a lawsuit seeking the release of 911 tapes Shannan made the night she went missing is still pending.

Director Liz Garbus, an Oscar-nominated documentarian, is making her narrative feature debut with the film. Producers Anne Carey and Kevin McCormick are collaborating on the project along with executive producers along with Amy Nauiokas, Rory Koslow.

Screenwriter Michael Werwie based the film on Robert Kolker’s book about the case, which is considered the largest unsolved homicide investigation in Suffolk history.

The Netflix release date comes after the film debuts Jan. 28 at the Sundance Film Festival. It will also be screened in select theaters, Netflix said. The announcement comes on the same day that Suffolk County police are revealing a previously undisclosed piece of evidence in the case for the first time since the remains were found a decade ago.
