How a Hollywood blockbuster was born from a director waiting for his star to lose weight
In short: When Robert Zemeckis needed to pause production on Cast Away to allow Tom Hanks to physically transform, he didn't stop working. Instead, he pivoted to a supernatural thriller, What Lies Beneath. The resulting film became a massive box office success, despite its director's mixed feelings about the script.
The origins of What Lies Beneath trace back to a personal paranormal experience by documentary filmmaker Sarah Kernochan. Her initial treatment envisioned an empty-nester couple encountering a ghost, aiming for a tone of wonderment similar to Close Encounters of the Third Kind. However, when the project reached director Robert Zemeckis, the vision shifted. Zemeckis, who had just rebranded his production company to ImageMovers, was looking for a thriller. He found the writing intelligent but felt the need to rework about three-quarters of the original screenplay, introducing a vengeful spirit plot that departed significantly from Kernochan's domestic focus.
The production schedule was dictated by the needs of Zemeckis’s other project, Cast Away. Because the team could not afford to hold the crew for a year while Tom Hanks lost weight and grew a beard, they filmed What Lies Beneath during the hiatus. Principal photography began in August 1999 in Vermont, with interiors shot on Los Angeles soundstages. Harrison Ford and Michelle Pfeiffer were the director's only choices for the leads. Ford, playing against his usual everyman persona, even withdrew from The Perfect Storm to commit to the role.
Upon its July 2000 release, the film became a commercial juggernaut, grossing over $291 million worldwide against a $100 million budget. It marked a milestone for Harrison Ford, who became the first performer to achieve domestic box office hits exceeding $100 million in each of four separate decades. Despite this, the film’s profitability was constrained by high production costs and talent payouts. Critics were divided, often praising Pfeiffer’s performance while criticizing the screenplay’s reliance on genre clichés and a supernatural ending that some felt undermined the film's Hitchcockian aspirations.
The film's legacy persists through its various home media iterations and its status as a piece of Hollywood efficiency. In 2025, a 25th-anniversary 4K edition was released, and writer Clark Gregg has since teased new developments set within the film's world. While it may not have been a critical darling, its ability to turn a production gap into a global success remains a notable case study in studio resourcefulness.
