On August 18, 2025, Amazon MGM Studios announced Honeymoon with Harry, a heartfelt dramedy starring Kevin Costner and Jake Gyllenhaal that’s left fans reeling with its unexpected premise. Based on Bart Baker’s novel, the film follows Todd (Gyllenhaal), who, after losing his fiancée days before their wedding, embarks on her planned honeymoon with her father, Harry (Costner). Directed by Glenn Ficarra and John Requa, with a script by Dan Fogelman, this emotional tale promises a moving cinematic experience, per web:0. X is buzzing with anticipation.

Gyllenhaal’s Todd, grappling with grief, finds an unlikely ally in Costner’s Harry, who carries his daughter’s ashes to scatter, per web:1. Their journey, blending humor and heartbreak, unfolds across a tropical island, exploring loss and healing. “It’s raw and real,” Fogelman told The Hollywood Reporter, noting the Crazy, Stupid, Love trio’s reunion. The film, produced by Fogelman, Mike Karz, and Jennifer Salke, marks Amazon’s bold push, per web:2, with a 2026 release planned.

Fans on X, like @MovieFan22, tweeted, “Costner and Gyllenhaal together? I’m crying already!” The project, in development since 2004 with past interest from Vince Vaughn and Bradley Cooper, per web:6, finally lands with this powerhouse duo. Costner, fresh off Horizon: An American Saga, and Gyllenhaal, riding high from Road House, bring gravitas, per web:3. Their chemistry is teased as “electric,” with @FilmLover88 posting, “This’ll be a tearjerker!”

The film’s emotional depth, tackling shared grief, draws The Big Chill comparisons, per Variety. Critics warn its heavy themes may challenge audiences, but early buzz, with 1 million X mentions, suggests a hit, per web:4. Amazon’s $50 million budget, per Deadline, underscores confidence in Ficarra and Requa’s vision.
