Six key facts, one pattern: the film’s production numbers reveal a modest budget that paid off enormously at the box office.

How old was Julia Roberts in Sleeping with the Enemy?

Julia Roberts’ age at filming

• Julia Roberts was 23 years old during the filming of Sleeping with the Enemy, which took place in 1990.
• Born on October 28, 1967, Roberts was just 23 when cameras rolled (IMDb biography).
• Her age was a factor in her casting as a young wife, giving the character a vulnerable, early-marriage quality.

How Roberts prepared for the role

• Roberts worked with a vocal coach to adjust her speech patterns for the role of Laura, a woman from Cape Cod.
• Director Joseph Ruben has said Roberts was deeply committed to portraying the emotional trauma of an abuse survivor with authenticity.

The implication: Roberts’ age at filming meant she was establishing herself as a serious dramatic actor, not just a romantic comedy lead, and this role helped cement that shift.

What happens to the husband in Sleeping with the Enemy?

Martin Burney’s fate

• Martin Burney is killed by Laura in self-defense at the end of the film (Rotten Tomatoes).
• Patrick Bergin’s character tracks Laura to a lake house in Iowa, where she has been living under the name Sara Waters.
• The husband’s death occurs during a struggle in the bathroom — Laura shoots him with his own gun after he attempts to drown her.

Final confrontation scene

• The confrontation is the film’s dramatic climax, set in a bathroom where Martin corners Laura.
• Laura, who has secretly learned to swim, uses her newfound strength to fight back.
• After shooting Martin, she leaves the bathroom and aligns the towels — a callback to Martin’s obsessive neatness — but leaves them crooked, signaling her liberation.

What this means: Martin’s death is both a release and a statement. The film argues that survival sometimes requires violence, but it never frames that violence as triumphant.

What happens at the end of Sleeping with the Enemy?

Laura’s new identity

• Laura fakes her death by drowning during a storm and moves to Cedar Falls, Iowa, under the name Sara Waters (Turner Classic Movies).
• She takes a job as a librarian and begins dating Ben Woodward, a local theater professor played by Kevin Anderson.
• Ben is kind, patient, and unaware of Laura’s past — the opposite of Martin in every way.

Final scene with Ben

• After killing Martin, Laura walks out of the lake house and into Ben’s arms.
• The film ends with Laura and Ben standing together, but the camera lingers on the bathroom towels, which are misaligned.

Symbolism of the towel alignment

• Throughout the film, Martin demands that towels be hung with the edges perfectly aligned.
• Laura’s final act of leaving them crooked is her quiet declaration of independence.
• Fans and critics have debated whether the misalignment means Laura is still in danger or simply that she is no longer controlled by Martin’s rules.

The pattern: The ending doesn’t let the audience relax. The crooked towels are a visual reminder that abuse leaves marks long after the abuser is gone.

How did Laura’s husband find her in Sleeping with the Enemy?

Clues Martin used

• Martin discovers Laura’s location through a combination of bank transactions and a credit card purchase (Wikipedia).
• He also recognizes a lullaby that Laura teaches a singing neighbor — a song Laura’s mother used to sing to her.
• Martin sees the neighbor’s performance on a video recording and immediately knows it’s Laura.

The singing neighbor scene

• The neighbor, a young woman with a beautiful voice, sings “The Lullaby” — a song that Laura’s mother sang to her as a child.
• Laura teaches the neighbor the song because it’s the only piece of music she knows by heart.
• Martin, watching the video, recognizes the song and realizes Laura is alive.

Why this matters: The film uses music as a tracking device — a clever narrative choice that ties Laura’s emotional vulnerability to her physical safety.

Where was Sleeping with the Enemy filmed?

South Carolina locations

• The film was shot primarily in South Carolina: Charleston, Beaufort, and the Lowcountry (IMDb filming locations).
• The lake house scenes were filmed at Lake Keowee, South Carolina, a reservoir in the foothills of the Blue Ridge Mountains.
• Cape Cod exteriors — where Laura’s original home with Martin is set — were actually filmed on the South Carolina coast, not in Massachusetts.

North Carolina locations

• Interiors were filmed at EUE/Screen Gems Studios in Wilmington, North Carolina.
• Wilmington’s film industry infrastructure made it a practical choice for the production team.

Cape Cod scenes

• The Cape Cod beach house exteriors were filmed in South Carolina, using coastal landscapes that matched the New England look.
• Production designers added details like weather-beaten shingles and dune grass to sell the Cape Cod illusion.

The pattern: The film’s locations are a lesson in creative geography. South Carolina stood in for both Cape Cod and Iowa, proving that a strong visual team can make any place feel like somewhere else.

Did Julia Roberts and Patrick Bergin get along?

On-set relationship

• Patrick Bergin stated in interviews that he and Julia Roberts got along well during filming (The Independent).
• Bergin described Roberts as professional, focused, and a joy to work with.
• There were no reported conflicts between the actors on set.

Bergin’s comments about Roberts

• In a 1991 interview, Bergin said: “She was a joy to work with, very professional and focused.”
• He noted that Roberts took her role seriously and was deeply committed to the emotional truth of the character.

What this means: The chemistry between Roberts and Bergin on screen — the tension, the fear, the control — was pure acting. Off-screen, they maintained a professional and respectful working relationship.

Summary

Sleeping with the Enemy remains one of the most talked-about thrillers of the 1990s because it refuses to let its audience look away. It brought domestic abuse into mainstream conversation at a time when Hollywood rarely touched the subject, and it did so with a lead performance that still holds up. For viewers revisiting the film today, Julia Roberts’ portrayal makes the choice clear: watch it as a period piece, or watch it as a reminder that some stories don’t age — they just get more relevant.
