From Paris Reunion to Cousins Beach Wedding: Everything We Know About The Summer I Turned Pretty Movie That Fans Have Dreamed Of.
The Summer I Turned Pretty, the beloved YA series that captured millions of hearts on Prime Video, is getting the cinematic ending it truly deserves. After the emotional Season 3 finale aired in September 2025, fans were left wondering if Belly Conklin’s story had truly concluded. The answer? Not even close. Prime Video and author Jenny Han have officially greenlit a feature film that will serve as the grand finale, picking up right where the series left off and delivering the long-awaited Belly and Conrad wedding that book readers have cherished for years.
The announcement came during the red carpet event for the Season 3 finale in Paris. Han, who is writing and co-directing the movie alongside co-showrunner Sarah Kucserka, explained that only a feature-length film could give the story the proper emotional weight and closure it needed. The script was already completed by December 2025, and principal photography began on April 27, 2026, in Wilmington, North Carolina — the real-life stand-in for the beloved Cousins Beach. Production is operating under the working title Blue Christmas, a detail that has sparked endless fan theories about holiday reunions and seasonal nostalgia.
The core cast is returning in full force. Lola Tung reprises her role as Isabel “Belly” Conklin, now fully stepping into adulthood. Christopher Briney returns as Conrad Fisher, the brooding older brother who finally won Belly’s heart in Paris. Gavin Casalegno is back as Jeremiah Fisher, who has moved on with his culinary dreams and a new relationship with a character named Denise. Fan favorites Sean Kaufman and Rain Spencer will also return as the beloved Staylor duo, whose storyline exploded with popularity in Season 3. The production is giving the young stars time to age naturally into more mature versions of their characters — Lola Tung is already 22 — which perfectly suits the time-jump elements reportedly in the script.
Plot details remain tightly under wraps, but Han has dropped enough hints to fuel excitement. The movie focuses on a major milestone in Belly’s journey — widely believed to be her wedding to Conrad. In the books, their wedding appears as a brief, beautiful epilogue. Here, that moment is being expanded into a full narrative that bridges the gap between the Paris reunion and a happily-ever-after at Cousins Beach. Fans can expect the iconic scene of the couple jumping into the ocean still dressed in their wedding attire, along with the long-awaited reading of Susannah’s handwritten letter, which Belly received but never opened during her near-wedding with Jeremiah.
The tone draws inspiration from romantic classics like Sleepless in Seattle, You’ve Got Mail, and Bridget Jones’s Diary — warm, hopeful, a little messy, but ultimately uplifting. Storylines will likely explore how Belly and Conrad’s relationship functions outside the emotional bubble of Cousins Beach and shared grief over Susannah. Jeremiah’s arc is also expected to receive a more fulfilling resolution, showing him thriving in his chef career rather than simply appearing as a supportive ex at the wedding. Early casting breakdowns mention roles for a Korean grandmother and young children (ages 5-7), strongly hinting at flashbacks and family expansion in the future.
Filming locations will feel like a homecoming for longtime fans. The Fisher beach house at Porters Neck Plantation, Wrightsville Beach, Crystal Pier, Casablanca Coffee Roasters, and Papercut Books are all back in action. The limited theatrical run — possibly in IMAX — before streaming on Prime Video marks a significant upgrade for the franchise, giving fans the big-screen experience the emotional story deserves. A 2027 release date is the current target, allowing time for polished post-production and maximum impact.
Cast reactions have been overwhelmingly positive mixed with genuine surprise. Lola Tung has described the role as far more than a job. Christopher Briney always believed Conrad and Belly belonged together. Gavin Casalegno admitted he was shocked by the Season 3 finale but is thrilled with the outcome. The cast reportedly only learned the true ending shortly before filming it, adding authenticity to their performances. Behind-the-scenes, the production has stayed relatively low-key to avoid spoilers, which has only heightened anticipation.
For fans, this movie represents closure and celebration. The series cleverly deviated from the books in Season 3 by moving the reunion to Paris and delaying the wedding, saving the most cinematic moments for the silver screen. Social media has been flooded with theories: Will we see more of Laurel and the Fisher family dynamics? How will the infinity necklace play into the final scenes? Will there be a Christmas-set reunion tied to the working title? Whatever the details, one thing is certain — the film promises to deliver the heartfelt, tear-jerking payoff that made the books and series such global phenomena.
The Summer I Turned Pretty began as Jenny Han’s trilogy and evolved into a streaming sensation that introduced a new generation to the magic of summer love, complicated family bonds, and growing up. This movie isn’t just fan service — it’s the creator giving her characters and audience the grand finale they earned. As cameras roll in Wilmington and excitement builds toward 2027, one thing is crystal clear: Cousins Beach still has one more unforgettable summer in store.
Whether you’re Team Conrad, Team Jeremiah, or simply Team Belly, the movie is poised to be the emotional event of the year for YA romance fans. Mark your calendars, rewatch the series, and get ready to say goodbye — or rather, hello forever — to the characters who stole our hearts under the summer sun.
