The Summer I Turned Pretty ended its third season on September 17, 2025. Soon after, the news landed that the story is moving into a feature film. Jenny Han is set to write and direct. During an appearance on the Today show, Lola Tung commented,

“We’ve known for a little bit but it’s fun that it’s finally out there in the world.”

Jenny Han also confirmed that she and co–showrunner Sarah Kucserka had already completed a draft of the script, saying,

“Sarah Kucserka, my co–showrunner, and I have finished a draft, so we’re chugging along."

This timing underlined how the production kept details close until the finale had aired. Fans watched the ending without confirmation of what came next, and the reveal added another wave of conversation. It was a strategy that helped keep attention fixed on both the conclusion and the promise of continuation.

Music at the center

One of the elements most associated with The Summer I Turned Pretty has been its music. In the finale, Jenny Han confirmed that Dress and Out of the Woods, both by Taylor Swift, were chosen to frame Belly and Conrad’s final arc on television. Dress played during their kiss in Paris. Out of the Woods was placed at the train station, when Belly chased Conrad down to declare her love. Han said the second track had been in her mind early, intended to highlight a moment of recognition for the character.

The Summer I Turned Pretty has used Swift’s catalog since its first season in 2022. Songs have acted as markers rather than decoration, pointing to shifts in characters and relationships. In the last episode, they worked like punctuation, closing a chapter while leaving space for the story to continue.


Paris and the fake scenes

Another part of the finale’s story came later. Gavin Casalegno, who plays Jeremiah, was filmed in Paris in scenes that were never intended to air. Images showed Jeremiah hugging Belly by the Seine, but Jenny Han later explained these were designed as decoys. They were not scripted moments, only a way to mislead onlookers and preserve secrecy around the real ending.

The decoy takes were shot alongside real material from episode 10. Casalegno compared the experience to undercover work, while fans spread theories based on the misleading footage. It was a calculated method to maintain surprise until the release date.

How Steven was seen

Steven, Belly’s brother, drew strong opinions in the final season. Viewers questioned why he seemed harsher on Conrad than on Jeremiah. Members of the cast defended the character. Christopher Briney said it was the first time he had heard such criticism. Lola Tung explained that Steven did not know all the details and acted out of protection for his sister. Sean Kaufman said he imagined Steven confronting Jeremiah off screen, and Gavin Casalegno agreed that it would have been unrealistic otherwise.

These comments do not change the script itself, but they frame Steven less as biased and more as loyal. The discussion shows how even secondary arcs shaped reactions to the finale.


Looking ahead to The Summer I Turned Pretty film

The feature film has been confirmed, but information remains limited. Jenny Han said a draft is complete but emphasized that production is still ahead. The cast has shared their own wishes. Sean Kaufman and Rain Spencer talked about wanting to see Steven and Taylor in San Francisco. Gavin Casalegno mentioned Jeremiah pursuing new passions, possibly connected to cooking. These are personal hopes rather than official directions, but they highlight where the actors see potential growth.

There is no filming schedule and no release window yet. Han confirmed that 2026 is not an option, which means fans will be waiting longer. Even so, the confirmation alone was enough to sustain interest.

Why it still resonates

The Summer I Turned Pretty kind of slipped into that space where everyone ends up talking about it. Not just for the romance on screen, but for the way it mixed drama with songs people already had in their playlists. It didn’t stop at the episodes either. There were those odd Paris moments, filmed just to throw people off, and the soundtrack that felt almost too perfect for the scenes. Then the finale, kept under wraps until the last second. Put together, it made the whole thing feel like it was living in two places: the part everyone saw and the part the cast and crew kept quiet, waiting for the right moment to show.


Conclusion

The television part feels closed now, but the movie is already pulling the story forward. The cast admitted they had heard about it a little earlier than the audience, even if the real confirmation only arrived once the finale was out. Between the songs that marked the big moments, the fake Paris shoots that fooled people online, and all the talk around Steven, the series shifts into something new. The Summer I Turned Pretty is heading into film, carrying a story that many already see as part of today’s pop culture.
