The Summer I Turned Pretty Movie: 5 Crucial Updates On The Release Date And Why Season 4 Was Canceled

The question on every fan's mind is no longer "When is Season 4?" but rather, "When will the movie sequel arrive?" As of December 2025, the highly anticipated feature-length film that will conclude the story of Belly, Conrad, and Jeremiah has a major update, but not the final release date everyone is hoping for. Show creator Jenny Han has confirmed that the script for the Prime Video movie is officially completed, moving the project one step closer to production, though filming has yet to begin.

The confusion over a "movie release date" stems from the fact that the original series, The Summer I Turned Pretty, has officially concluded its three-season run. The third and final season, which adapted the third book, We'll Always Have Summer, premiered in July 2025 and ended on September 17, 2025. The movie sequel, announced immediately after the series finale, is a surprise continuation that promises to deliver a definitive ending to the beloved love triangle, leaving fans of both Team Conrad and Team Jeremiah (or Bonrad and Jelly) on the edge of their seats.

The Summer I Turned Pretty Movie Release Date: The Latest Official Update

The news that The Summer I Turned Pretty would not return for a Season 4 was confirmed by Prime Video and author Jenny Han herself, as the three seasons successfully adapted all three books in her original novel trilogy. However, the story will not end there. A feature-length film, tentatively titled The Summer I Turned Pretty: The Movie, has been greenlit to serve as an epilogue or a follow-up to the events of Season 3, giving the narrative a true cinematic conclusion.

• Official Status (December 2025): The script for the movie sequel is officially finished.
• Production Timeline: As of the latest updates, production has not yet started. This means the movie is still in the pre-production phase, focusing on casting confirmation, location scouting, and scheduling.
• Release Date: There is currently no set release date for The Summer I Turned Pretty Movie. Given the script is just completed and production hasn't started, a release is unlikely to happen in the first half of 2026. The earliest realistic window would be the Summer of 2026 or later, depending on the production schedule.
• Source Material: The movie will be an original story, expanding beyond the final novel, We'll Always Have Summer, which the third season covered. This makes the plot entirely new, even for book fans.
• Cast Confirmation: It is confirmed that the main cast will return, including Lola Tung as Belly Conklin, Christopher Briney as Conrad Fisher, and Gavin Casalegno as Jeremiah Fisher.

The shift from a final season to a movie allows the creative team to give the story a higher-budget, more focused, and climactic finale. Fans should follow official announcements from Prime Video and Jenny Han for the moment filming begins, as that will be the first major indicator of a potential release window.

Why The Summer I Turned Pretty Ended with a Movie, Not a Season 4

The decision to conclude the main series run after Season 3 was not a cancellation but a natural conclusion based on the source material. The original book series by Jenny Han is a trilogy, meaning there are only three novels to adapt. Season 1 covered The Summer I Turned Pretty, Season 2 covered It's Not Summer Without You, and Season 3 covered the final book, We'll Always Have Summer.

The feature-length movie is an exciting, unprecedented move that allows the story to continue beyond the page. It’s an opportunity for Han and the writers to explore a completely new chapter for Belly Conklin and the Fisher brothers, potentially years after the events of the third book. This could finally settle the intense Team Conrad vs. Team Jeremiah debate that has fueled the show's popularity on social media. The movie format gives the creators the freedom to craft an emotionally resonant, high-stakes finale without the constraints of a full season run.

This decision is similar to how other beloved book-to-screen adaptations, like the Harry Potter series, used an expanded format to conclude their stories, ensuring every fan-favorite moment and emotional beat is given the screen time it deserves. The movie is seen as a way to give the characters the final, satisfying send-off they—and the dedicated fanbase—deserve.

• Cousins Beach: The central, idyllic, and fictional coastal town where the Conklin and Fisher families spend their summers. It is the emotional heart of the series, representing everything from childhood innocence to first heartbreak.
• Wilmington, North Carolina: The primary real-world filming location for the series. While Cousins Beach is fictional, the majority of the scenes, including the iconic beach house, were filmed in and around Wilmington and the surrounding areas.
• Jenny Han: The author of the original novel trilogy and the showrunner, executive producer, and writer for the Prime Video adaptation. Her creative vision is the driving force behind the entire franchise, including the upcoming movie sequel.

While the wait for the movie release date is frustrating, the fact that the script is done is the strongest indication yet that the final chapter of Belly's story is imminent. Fans can rest assured that the creative team is working to deliver a fresh, satisfying conclusion that will finally answer the central question of the series.
