Upcoming conclusion: Feature film (announced)

Eight key facts at a glance: from the series’ creator to the upcoming film.

Will there be a season 4 of The Summer I Turned Pretty?

No. Prime Video ended the series after season 3. The final episode of season 3 was released on the platform on September 17, 2025 (Ouest-France Programme TV). Instead of a fourth season, the streamer announced a feature film to wrap up the story.

Jenny Han, the author of the original trilogy, has said the three seasons told the core story. At the Paris red carpet event for the season 3 finale, Prime Video confirmed the film would serve as the series finale (Ouest-France Programme TV). Han explained that a film was needed to “do justice to Belly’s final story step.” The decision to end after season 3 came from creative intent, not low viewership.

Why was the series not renewed for a fourth season?

What is the upcoming film about?

The film will continue the story of Belly, Conrad, and Jeremiah beyond the events of season 3. During the announcement event in Paris, actors Lola Tung (Belly) and Christopher Briney (Conrad) posed in front of a sign reading “L’été où je suis devenue jolie, le film” (Ouest-France Programme TV). Gavin Casalegno (Jeremiah) is also expected to return. The film’s plot remains under wraps, but the season 3 finale included a teaser with photos of Belly and Conrad and a letter from Jenny Han that ends with “Peut-être nous reverrons-nous à Cousins?” — hinting at a return to the beach house setting.

Why is season 3 of The Summer I Turned Pretty considered bad?

Fan reactions to season 3 have been mixed, largely because of deviations from Jenny Han’s books. One major complaint: a key scene from the novel — Belly’s inner monologue about why she chooses Conrad — was omitted from the finale (Programme TV). Critics also pointed to rushed pacing and a cliffhanger that shifts the emotional weight to the film.

Critical reception of season 3

Reviews have been less enthusiastic than for seasons 1 and 2. The truncated format — ending the series within a single season — left some arcs feeling incomplete. Rotten Tomatoes user scores for season 3 are not yet available, but social media discourse highlights frustration with the abrupt transition to a film.

Fan reactions and book deviations

The omitted inner-monologue scene is a prime example. In the book, Belly’s reflection on Conrad grounds her decision. Without it, the finale’s emotional payoff felt weaker to many readers (Programme TV). The positive side: the film can restore that depth.

The pattern: rushed finales often leave fans wanting more, but can open doors for extended storytelling.

Will Belly and Conrad end up together?

Yes. The series finale adapts the ending of Jenny Han’s third book, in which Belly chooses Conrad. The season 3 finale depicts their reconciliation, and the upcoming film is expected to maintain that outcome (Ouest-France Programme TV).

Book ending vs series ending

Jenny Han’s original trilogy ends with Belly and Conrad married years later. The series mirrors this: by the end of season 3, Belly and Conrad are together after years of back-and-forth. The film will likely show their future, perhaps skipping ahead as the novels did.

Finale spoilers

In the final episode, Belly and Conrad reunite at Cousins Beach. The episode includes flashbacks to their childhood and a voiceover from Belly confirming her choice. The teaser for the film shows a photo of the pair and a letter from Han.

Who is older, Conrad or Jeremiah?

The age order between the Fisher brothers has been a recurring question. In season 1, Conrad is a senior in high school while Jeremiah is a junior. This difference shapes their maturity and interactions.

Age differences in the series

The timeline of the show spans several summers, but the relative ages remain consistent. Conrad is a senior in high school when Belly is a sophomore, which influences their emotional maturity. Jeremiah, though younger, is more carefree.

Character dynamics

Conrad’s age and sense of responsibility often make him withdrawn. Jeremiah’s youth makes him more open. The age difference is a subtle but real driver of Belly’s shifting affections throughout the three seasons.

Which film features Jeremiah and Conrad?

The announced feature film — currently untitled but marketed under the banner “L’été où je suis devenue jolie, le film” — will bring back both brothers. Lola Tung, Christopher Briney, and Gavin Casalegno are all reported to reprise their roles (Ouest-France Programme TV). The film is another Prime Video adaptation, similar to Verity (Film) – Cast, Director, Release Date & Book Adaptation, which also turns a popular book franchise into a movie.

The announced film

Prime Video revealed the project on September 17, 2025, at a red carpet event in Paris. The series creator Gabrielle Stanton and author Jenny Han attended. The film is described as the “grand finale” of the story.

Expected release date and cast

No release date has been set. Production is expected to begin in 2026. The core cast is expected to return, along with other recurring characters like Susannah (played by Rachel Blanchard) and Laurel (Jackie Chung).

The pattern: the series wrapped up in three years, with a film capping the story.

Quotes from the key players

“A film was needed to do justice to Belly’s final story step.”

— Jenny Han, author of the original trilogy, at the Paris event (Ouest-France Programme TV)

“Peut-être nous reverrons-nous à Cousins?”

— Jenny Han’s letter to fans, included in the season 3 finale (Ouest-France Programme TV)

The takeaway: Han’s commitment to the story remains strong, even as the format shifts.

The choice to end the series with a film rather than a full season was driven by narrative ambition, not ratings. For fans invested in Belly and Conrad’s love story, the film promises closure — but only time will tell if Jenny Han’s extended universe continues beyond that. For Prime Video, the gamble is clear: either the film becomes a satisfying capstone, or audiences will feel shortchanged by the truncated series.
