The transition of the hit Prime Video series The Summer I Turned Pretty into a feature-length cinematic conclusion marks a significant shift in Amazon MGM Studios’ strategy for its high-performing young adult (YA) intellectual property. Following the conclusion of the series’ third season, production has officially shifted to a film format to chronicle the final chapters of Isabel "Belly" Conklin’s journey. This move, orchestrated by series creator and author Jenny Han, aims to provide a more expansive, high-production-value finale to a franchise that has become a cornerstone of modern streaming culture. As the project moves through its principal photography phase in various East Coast locations, the production has garnered significant attention regarding its casting, financial arrangements, and the narrative direction of its final act.
Production Timeline and Development History
The roadmap for The Summer I Turned Pretty movie was established in late 2025, coinciding with the release of the Season 3 finale. While fans initially speculated that the third season would conclude the narrative, Amazon MGM Studios confirmed that an additional feature film would serve as the definitive "final chapter." Jenny Han, who serves as the primary architect of the franchise, has been vocal about the necessity of this format change. During an appearance at TheWrap’s Power Women Summit in December 2025, Han clarified the project’s status, noting that the screenplay had been completed but that physical production was intentionally delayed to ensure the quality of the final product.
Initial fan theories suggested a surprise release in late 2026, perhaps as a holiday event. However, Han debunked these rumors, citing the rigorous post-production schedule of Season 3 as a limiting factor. "We wouldn’t have had time to film a whole movie," Han explained, emphasizing that the production required its own dedicated window to achieve the "milestone" moments required for the story. This led to the official commencement of filming on April 27, 2026. Given the current production trajectory, industry analysts suggest a premiere date in mid-to-late 2027, allowing for a summer release window that aligns with the franchise’s seasonal branding.
Filming Locations and Logistical Challenges
The production of The Summer I Turned Pretty movie has utilized a dual-location strategy to balance practical studio needs with narrative authenticity. Since the series’ inception, Wilmington, North Carolina, has served as the primary stand-in for the fictional town of Cousins Beach. Principal photography for the film began in Wilmington, utilizing the region’s coastal landscapes and established sets that fans have come to associate with the Fisher and Conklin families.
In June 2026, production expanded to New England, specifically Plymouth, Massachusetts. This move is significant for the narrative, as the fictional setting of the books is located in New England. Filming in Massachusetts provides an added layer of geographical authenticity for scenes that may take place outside the immediate vicinity of the Cousins Beach summer house.
However, the popularity of the franchise has created unique logistical hurdles for the crew. On May 5, 2026, the production’s official social media channels issued a plea for privacy. The statement addressed concerns regarding fans traveling to active sets and sharing location data in real-time. "Sharing locations and visiting set disrupts filming and creates real safety concerns for our cast and crew," the statement read, emphasizing the need for a "protected bubble" to maintain the "magic of Cousins." This level of fan engagement, while a testament to the show’s success, has required increased security measures and more secretive filming schedules.
Cast Returns and Financial Negotiations
The core "love triangle" that drives the franchise—composed of Lola Tung (Belly), Christopher Briney (Conrad), and Gavin Casalegno (Jeremiah)—is confirmed to return for the feature film. Supporting cast members, including Rain Spencer (Taylor), Sean Kaufman (Steven), Jackie Chung (Laurel), and Tom Everett Scott (Adam Fisher), are also expected to reprise their roles to provide closure to their respective character arcs.
The transition from a streaming series to a feature film brought about significant contract renegotiations. According to industry reports from Deadline, the lead trio secured substantial salary increases as part of a package deal tied to Season 3 and the subsequent movie. While Prime Video does not publicly disclose specific salary figures, reports indicate that Tung, Briney, and Casalegno earned approximately $100,000 per episode for the 10-episode third season.
For the movie, the actors are reportedly being paid "three episodic fees," which translates to roughly $300,000 each for the single feature project. Lola Tung, as the central protagonist, is believed to have negotiated a higher overall compensation package. These figures reflect the high value Amazon MGM Studios places on the cast’s continuity, particularly as the actors’ individual profiles have grown significantly since the show’s 2022 debut.
Narrative Direction: The "Big Milestone"
The plot of the movie is expected to draw heavily from the third and final book in Jenny Han’s novel trilogy, We’ll Always Have Summer. The Season 3 finale left several threads open: Belly chose to pursue her relationship with Conrad, Jeremiah began a new chapter involving a culinary career and a budding romance with a character named Denise, and Taylor and Steven made plans for a move to California.
The central mystery surrounding the film involves what Han describes as a "big milestone" for Belly. In the source material, this milestone is a wedding, though the books involve a complex series of events including a time jump and a broken engagement before the final resolution. Han has teased that only a movie format could give this specific milestone its "proper due."
Co-showrunner Sarah Kucserka and Han have completed the screenplay, which aims to balance the expectations of book loyalists with the established continuity of the television adaptation. Analysts expect the film to utilize a more cinematic visual language, moving away from the episodic structure of the show to focus on a singular, high-stakes narrative arc that concludes the "coming-of-age" journey of the protagonist.
Broader Impact on the Streaming Landscape
The decision to conclude The Summer I Turned Pretty with a movie is emblematic of a broader trend in the streaming industry. Platforms are increasingly looking for ways to "eventize" their most successful series. By transitioning to a film, Prime Video can leverage a more concentrated marketing campaign and potentially explore limited theatrical engagements, a strategy that has proven successful for other streaming-first properties like Don’t Look Up or Glass Onion.
Furthermore, the success of the Jenny Han "universe" at Prime Video—which also includes the spin-off series XO, Kitty on Netflix—demonstrates the enduring power of the YA demographic. Courtney Valenti, head of film, streaming, and theatrical at Amazon MGM Studios, and Vernon Sanders, global head of television, emphasized this in a joint statement, noting that the series has created "moments of joy, nostalgia, and connection" on a global scale.
The film serves not just as a conclusion for fans, but as a high-value asset for the Prime Video library, ensuring long-term viewership as new audiences discover the series and progress toward the cinematic finale. As filming continues through the summer of 2026, the production remains one of the most high-profile projects in the Amazon MGM pipeline, representing a significant investment in talent and brand loyalty.
Conclusion and Future Updates
As production moves forward in New England and North Carolina, the "bubble" around the set remains tight. Fans can expect continued teases from official channels, but the core plot details and the exact release date remain closely guarded secrets. The Summer I Turned Pretty movie stands as a testament to the power of literary adaptations in the digital age, proving that even in a crowded marketplace, a well-executed coming-of-age story can command the resources and attention of a major motion picture. Further updates regarding official casting additions and the debut of the first teaser trailer are expected once principal photography concludes in late 2026.
