Prime Video has officially given the go-ahead to The Summer I Turned Pretty movie. It is a feature-length finale designed to cap Belly’s story after the show’s third season. In a TODAY interview, series creator and author Jenny Han framed the film as the right format to deliver true closure. She also thanked viewers for carrying the story through its TV run.

What Prime Video Greenlighting a Tsitp Movie Means

USA Today reports that Prime Video has greenlit a The Summer I Turned Pretty feature to follow the televised finale. They are positioning it as a final chapter rather than an ongoing fourth season. The outlet also notes that there is no confirmed release date yet. Therefore, questions like “when is the summer i turned pretty movie coming out” and “when will the summer i turned pretty movie come out” remain unanswered for now. 

Why Make a Movie Instead of Season 4?

There is no “The Summer I Turned Pretty season 4.” Instead, the streamer opted for a film. That aligns with how the source trilogy was always meant to end. It gives Han space to finish key arcs without stretching the story. In that same spirit, the TODAY conversation suggested the movie is less about resetting the love triangle and more about landing the emotional themes. These themes drew fans in from the start: first love, grief, and growing up. “The Summer I Turned Pretty, the movie,” is meant to feel like a culmination, not a detour.

How The Show Became 2025’s Surprise TV Hit

To understand why a feature makes sense, look at the show’s reach. The series tapped a wave of millennial nostalgia with its earnest tone, coming‑of‑age stakes, and a soundtrack that helped scenes linger in memory. That resonance—along with weekly communal viewing—turned the finale into an “event.” It is the kind that naturally paves the way for a feature-sized farewell.

Cast Vibes: Who We Expect to See

Christopher Briney returns as Conrad, Gavin Casalegno as Jeremiah, and Rain Spencer also returns in her role. These three were major parts of the TV series’ emotional arcs, especially in season 3, which jumped ahead in time and revisited unresolved feelings.

While formal casting is typically announced closer to production, fan focus remains on Christopher Briney and Gavin Casalegno as the Fisher brothers. Fans also focus on Rain Spencer and Lola Tung (Isabel Conklin). The TODAY segment centered on the creative hand of Jenny Han and the promise of resolution. USA Today’s coverage reinforced that this will serve as the definitive capstone for Belly’s story. Until the studio provides a casting release, treat returns as extremely likely but not yet confirmed.

Release Timing: What We Can and Can’t Say Yet

If you’re searching for The Summer I Turned Pretty movie release date or the exact TSTP movie release date, there isn’t one publicly set. That means questions like “when does The Summer I Turned Pretty movie come out?” still don’t have a precise answer. USA Today characterizes the project as moving forward at Prime Video, but without a calendar stamp attached. When the platform announces a date window, we’ll update this page.

Here’s where things are still murky:

  • No official release date has been announced for the film. 
  • However, Jenny Han told The TODAY Show that the movie is not expected in 2026
  • That suggests a likely release window in 2027 or later, though that is not confirmed. 

Background: Series Finale, Season 3 & End of the Line

The Summer I Turned Pretty TV series concluded with its third season on Prime Video. The final season—season 3—began streaming on July 16, 2025, with 11 episodes and ended on September 17, 2025

After the finale aired, Jenny Han announced in Paris during a finale celebration that a movie would be the best way to give Belly’s story its full, satisfying close. Han said there was “another big milestone left in Belly’s journey, and I thought only a movie could give it its proper due.” 

What We Still Don’t Know

  • The exact plot details of the movie are under wraps—though there is speculation it might cover the omitted wedding scene between Belly and Conrad (a milestone in the book series) and wrap up arcs left open from the finale. 
  • We don’t yet know when filming will begin, where much of the film will be shot, or its precise premiere timeline. 

Why TSITP Movie Matters to Fans

For viewers who watched the TV finale and asked whether a film could deliver the last, book‑faithful beats, the greenlight is encouraging. The Guardian’s read on the fandom—fueled by nostalgia and big feelings—explains why the appetite is there. The movie aims to reward that investment with a closing chapter, rather than reopening old questions.
