COUSINS BEACH IS CALLING ONE LAST TIME! 🌊💍🚨 The show might be over, but the story isn’t. “The Summer I Turned Pretty: The Movie” is officially HAPPENING and I’m a mess.

I thought I was done crying after the Season 3 finale, but Prime Video just dropped a “Sneak Peek” that proves some loves are forever. 😭 It’s been months since we saw Belly and Conrad back at the summer house, but the movie is taking us to the one place we’ve all been waiting for: THE WEDDING. 👰✨ Jenny Han confirmed this is the “final milestone” for Belly, and seeing Lola Tung in that white dress (even for a split second) has the entire fandom in a chokehold.

Is it finally Conrad? Is Jeremiah really okay with how things ended? The production starts this April 27, and the rumors of a late 2026 release are basically all I’m living for right now. 🥂✨

Watch the “Final Milestone” Sneak Peek and see the wedding theory breakdown here: 👇🔥

For three seasons, fans have watched Isabel “Belly” Conklin (Lola Tung) navigate the turbulent waters of first love, grief, and the complicated Fisher brothers. While many assumed the Season 3 finale—which saw Belly and Conrad (Christopher Briney) reuniting at the Cousins Beach house—was the end of the road, Prime Video has pulled off one last “summer surprise.” On April 2, 2026, it was officially announced that The Summer I Turned Pretty will conclude with a feature-length film, skipping a fourth season to give the story a “cinematic closure.”

The “Big Milestone”: A Wedding at Cousins?

Author and director Jenny Han has been cryptic but intentional with her teasers. During a recent red carpet event in Paris, Han stated, “There is another big milestone left in Belly’s journey, and I thought only a movie could give it its proper due.”

For readers of Han’s original trilogy, specifically the final book We’ll Always Have Summer, the “milestone” is almost certainly the long-awaited wedding between Belly and Conrad. While Season 3 touched on the chaotic lead-up to a potential wedding with Jeremiah (Gavin Casalegno), the film is expected to focus on the maturity and “adulthood” of the characters as they finally commit to their forever.

Production Timeline: April 27 Kickoff

The movie is slated to begin principal photography on Monday, April 27, 2026, in its long-time home of Wilmington, North Carolina. This quick turnaround from the Season 3 finale suggests that the script—co-written by Han and Sarah Kucserka—was fast-tracked to capitalize on the series’ record-breaking viewership numbers.

“I always wanted some distance for the movie,” Han explained to Variety. “Giving the actors a little breathing space to get closer to adulthood makes the transition from ‘coming-of-age’ to ‘grown-up’ feel authentic.” With Lola Tung now 22, the film will likely feature a slight time jump to reflect the characters’ post-college lives.

Cast and New Directions

The core “Big Three”—Lola Tung, Christopher Briney, and Gavin Casalegno—are all confirmed to return. However, the film will also explore the burgeoning life of Jeremiah, who was last seen pursuing a culinary career and finding a new romantic spark with Denise (Isabella Briggs).

On r/TSITP, the community is buzzing about whether the movie will include the “missing letters” from the book series—the correspondence between Belly and Conrad during their years apart. “If we don’t get a montage of the letters, we riot,” joked one top-voted Reddit user.

Release Date Speculation: Christmas 2026?

While Prime Video has not set a definitive premiere date, industry analysts at Deadline and ScreenRant are eyeing a late 2026 or early 2027 release. Despite Jenny Han previously debunking a “surprise holiday drop” for 2025, the late-April filming start makes a Christmas 2026 release technically possible, fitting the “Last Christmas” theme that has become a staple of the franchise.

A Cultural Phenomenon Reaches Its Peak

Since its debut in 2022, The Summer I Turned Pretty has been a cornerstone of Prime Video’s Young Adult programming. The decision to pivot to a movie for the finale mirrors the strategy used by other successful franchises, aiming to turn a television “event” into a global theatrical or streaming “spectacle.”

As the cast returns to Wilmington this week, one thing is certain: Cousins Beach still has one more story to tell, and it’s the most important one yet.
