Prime Video announced TSITP: The Movie, a feature-length extension of The Summer I Turned Pretty, shortly after the third and final season concluded. The project will be directed by Jenny Han and written by Han alongside Sarah Kucserka, with Han framing it as the final milestone in Belly’s journey that a movie format can uniquely honor. The news confirms the franchise’s move beyond episodic television to a cinematic chapter as fans await how the romance-centered universe will cap Belly’s arc.
Details about the production timeline remain scarce, but Han offered a cautious timetable during a visit to The Today Show from Paris. She said it is still too early to specify a premiere date and that a 2026 release is unlikely. For now, the earliest return to Cousins Beach for the movie appears to be 2027. Producers have not begun filming; hashing out the script is the current priority. Han and Kucserka have completed a first draft and are in the process of revising it, while the team maps out the film’s structure and scope.
Specific plot points for TSITP: The Movie are being kept under wraps. The Season 3 finale left several scenes and an epilogue out of the narrative, prompting speculation about Belly’s next steps and the relationships that could feature in the film. Fans familiar with the source material know that Book 3, We’ll Always Have Summer, contains key moments that could inform the movie’s direction, though the adaptation has room to introduce new elements and relationships that were teased at the end of the series. Possible threads include Belly’s future career ambitions, the potential for new settings such as Paris during Christmas, and evolving dynamics involving Conrad, Jeremiah, the Denises, and other Island characters. The team has signaled that the final chapter will seek to honor the emotional core of the books while expanding the universe for a movie audience.
Industry observers note that moving a beloved book-into-film finale into production typically requires careful pacing, especially when writers and producers want to preserve the tone and character arcs that fans have grown attached to. With writing underway and filming not yet scheduled, the project is in the early development phase, and a concrete start date remains undetermined. In the meantime, all three seasons of The Summer I Turned Pretty remain available on Prime Video, giving new and returning viewers a chance to revisit the series before the movie arrives. Prime Video’s involvement underscores the studio’s commitment to the franchise’s expansion and to bringing Belly’s story to a broader audience.
Fans and industry watchers will await formal updates from Prime Video and the creative team as the project progresses from draft revisions to production planning and, eventually, a release timeline. For now, the absence of a firm premiere date is the status quo, with a 2027 window noted by the show’s creator as the earliest likely moment for re-entry to Cousins Beach. Updates are expected to come as the writing and production plan take shape, with more concrete information to be shared when available.
