After over a decade away from Hollywood, Cameron Diaz has stormed back into the spotlight with back-to-back projects, already dominating the 2025 slate with action-packed returns like Back in Action and Bad Day. And just as her comeback finds its rhythm, 2026 is set to bring a softer, more classic turn, as Diaz steps into the world of romance with an upcoming untitled rom-com, adding a fresh layer to her third act.

Here’s everything you need to know about her Diaz's untitled rom-com, including its release, plot, and cast.

Yet to be titled, Cameron Diaz’s 2026 romantic comedy is directed, co-written, and co-starring Stephen Merchant, bringing a fresh romantic turn to her epic return. Bringing with it a quiet promise of love, chaos, and unexpected turns, the project is currently unfolding across New York City, with filming underway in the West Village and along the Hudson River, where the duo has been spotted throughout March 2026. And while the release date remains tightly under wraps, the film has already begun building intrigue, hinting at a story where love might just come with its own unexpected complications.

Backed by Amazon MGM Studios and produced by Point Grey Pictures (Seth Rogen and Evan Goldberg), Diaz’s comeback has moved at full speed since her 2014 exit, returning with Back in Action alongside Jamie Foxx in 2025 and quickly following it up with Bad Day. Before her hiatus, Diaz was one of Hollywood’s biggest stars, rising with The Mask and delivering hits like There's Something About Mary and Charlie's Angels, building a two-decade career across over 40 films before stepping away after Annie.

As Cameron Diaz gears up to blend romance and drama, what is the story set to unfold behind this curtain of love, and who are the faces joining her in bringing it to life?

Recently spotted filming in New York City, Cameron Diaz was seen in character on March 13, dressed in a long black leather coat, scarf, and lace-up boots, with early glimpses already sparking buzz around her on-screen chemistry with Stephen Merchant. The film follows a classic rom-com setup with a twist, where a workaholic British hotel executive enters a fake marriage with Diaz’s struggling stand-up comedian, a deal driven by convenience that slowly unravels into something far more complicated and unexpectedly romantic. Backed by producers like Lee Eisenberg, Seth Rogen, and Evan Goldberg under Point Grey Pictures, the project guarantees high-quality comedic storytelling.

Joining Cameron Diaz and Stephen Merchant is a strong ensemble featuring Rob Lowe, Judith Light, Josh Segarra, and Sherry Cola, with further additions like Fabrizio Guido, Lisa Gilroy, Myra Lucretia Taylor, and Dustin Ybarra rounding out a cast that hints at a lively, multi-character story unfolding.

As Diaz continues her comeback era, the upcoming 2026 rom-com has already started sending onlookers into a frenzy, with early glimpses and on-set buzz hinting at a story filled with romance, tension, and an undeniable pull.
