October 7, 2025: Fans of the hit Prime Video series The Summer I Turned Pretty have a big reason to be happy. The story of Isabel “Belly” Conklin will not end with Season 3.
Prime Video has officially said that a feature film is coming. This movie will be the final part of Belly’s emotional journey. The news came just after the series finale was streamed on September 17, 2025.
“Another Big Milestone” Awaits for The Summer I Turned Pretty
Jenny Han, the creator and author of the original book trilogy, confirmed the news. She said that a movie is the best way to properly conclude Belly’s story. “There is another big milestone left in Belly’s journey,” Han stated.
She felt that only a movie could give this final chapter the importance it deserves. This hint has made fans guess what the movie will be about. Many believe the film will show the long-awaited wedding of Belly and Conrad.
A Look at the Possible Plot
The TV series is based on Han’s bestselling books. The third season adapted the final book, We’ll Always Have Summer. However, it did not show Belly and Conrad getting married, which happens in the book’s epilogue.
The Season 3 finale showed Belly, played by Lola Tung, choosing Conrad Fisher, played by Christopher Briney. A flash-forward scene showed the couple years later, returning to the beloved Cousins Beach house.
Since the wedding was missed in the series finale, it is very likely to be the “big milestone” in the movie. The film is expected to show the deepening relationship between Belly and Conrad. It will give a final, mature, and satisfying end to their love story. It will also give closure to the love triangle that has kept viewers hooked for three seasons.
Key Cast Members Will Return
Prime Video has confirmed that Lola Tung and Christopher Briney will be back as Belly and Conrad. This ensures that fans will see their favorite characters played by the same actors as they move into adulthood.
The movie will follow their journey from young love to a final commitment. The full cast list for the movie has not been fully announced yet. But, we can expect to see other fan-favorite characters returning to Cousins Beach one last time.

No Quick Release Date Expected for The Summer I Turned Pretty Movie
Jenny Han gave some updates on the movie’s production. She mentioned that a first draft of the script is ready. Han and co-showrunner Sarah Kucserka have been working on it. However, fans will have to be patient. Han said that the film is “not next year.”
She added that the delay is intentional. She wants more time so the actors can get closer to their characters’ older ages in the story. This extra time will help make the final chapter feel more complete and real for the audience. The official release date is yet to be announced by Prime Video.
The Summer I Turned Pretty has been a huge success for Prime Video. It became one of the platform’s most-watched returning seasons. The movie is seen as a thank-you to the loyal fans. It will bring Belly’s coming-of-age story to a proper and special end on the big screen.
