Finale Of 'The Undoing', Filmed On North Fork, Has Fans Abuzz

EAST MARION, NY — Forget the Thanksgiving holiday weekend, the coronavirus pandemic, a looming storm and political tensions — the one topic that had social media buzzing Sunday night was the series finale of HBO's "The Undoing," starring Nicole Kidman and Hugh Grant.

Without giving away spoilers, the ending brought viewers on a suspenseful roller coaster fueled by powerhouse performances by Kidman and Grant — in acting turns many deemed Emmy worthy — as audiences finally learned, after weeks of twists and turns, who killed Elena Alves.

And the answer had the internet on fire.

"'The Undoing': Check you out, Hugh Grant. Wow!" Bonnie Grice wrote on Facebook.

"I'm undone!" wrote Eileen Kapell, also on Facebook.

"Best whodunit show all year," Drew Scott added.

Another woman wrote she went through her house removing anything that looked remotely like a hammer.

Indeed, the series finale's shocking ending hinged on one very important piece of evidence: A sculpting hammer belonging to Alves was found in the fire pit of the summer home belonging to Kidman's character's father, played by Donald Sutherland.

Those riveted by the series found scenes filmed at that summer home and on the rock-strewn waterfront familiar: The series was shot in 2019 on the North Fork, with the Long Island Sound providing a haunting backdrop for the suspenseful drama.

The summer home where Nicole Kidman's character retreats with her son after learning the shocking news that her husband has been unfaithful and is a suspect in a woman's murder is located on Rocky Point Road in East Marion.

"The Undoing" marks a reunion between Kidman and "Big Little Lies" creator David E. Kelley. The series is directed by Susanne Bier. "The Undoing" is based on the book "You Should Have Known" by Jean Hanff Korelitz.

Also featured in the cast are Edgar Ramirez, Lily Rabe, Ismael Cruz Cordova, Matilda DeAngelis and Noma Dumezweni.

The series, which debuted Oct. 25, focuses on Grace Sachs, a successful therapist played by Kidman.

"The limited series follows Grace (Kidman) and Jonathan Fraser (Grant), who are living the only lives they ever wanted for themselves," a news release from HBO said. "Overnight, a chasm opens in their lives: a violent death and a chain of terrible revelations. Left behind in the wake of a spreading and very public disaster and horrified by the ways in which she has failed to heed her own advice, Grace must dismantle one life and create another for her child and her family."

In a post on HBO .com, Kidman said, "David has created another propulsive series with a fascinating, complicated female role at its center."

According to the Southold Town website, the summer home was "for over 50 years, headquarters of a life-saving station which rescued countless people who otherwise would have been lost when their ships were wrecked off the sound shore. The United States Coast Guard was in charge of the station during World War II."

Kidman has filmed on the North Fork in the past: In 2007, she delighted fans who waited for hours for a glimpse as she filmed a scene at the Long Island Rail Road station in Greenport for "Margot at the Wedding."
