Gavin Casalegno Nearly Backed Out of a Pivotal Season 3 Scene Before The Summer I Turned Pretty Movie
As The Summer I Turned Pretty eyes the big screen, Gavin Casalegno is still second‑guessing one season 3 choice: Jeremiah Fisher’s rapid rebound with newcomer Denise Russo right after his broken engagement to Belly.
Gavin Casalegno is already thinking about The Summer I Turned Pretty movie, but he is still stuck on one season 3 choice that did not sit right with him. Honestly, I get it.
Gavin is not sold on Jeremiah's rebound
Casalegno, 26, told Us Weekly he hesitated over Jeremiah Fisher jumping into something new with Denise Russo right after Belly and Jeremiah called off their engagement. He is not out here giving his character life advice, but even he flagged how little time passes before Jeremiah moves on. In other words: fun for drama, tough for believability.
That hesitation lands as the show aims for a feature-length finale and, in real life, Casalegno is doing the opposite of rebounding. He is newly married and keeping things pretty low-key off camera.
The movie is happening, and it is the endgame
Prime Video greenlit a feature film continuation shortly after the season 3 finale hit the platform. Jenny Han is writing and directing it herself, which is a very clear signal: this is the final chapter for Belly Conklin, not a stealth season 4.
Han told Variety she wanted to return to the story when the cast was 'a little bit closer to adulthood.'
The movie will pick up after the events of season 3, not reboot anything. Speaking of that finale: we left off with Belly and Conrad reconnecting in Paris years after their split, then a flash-forward to cozy holiday vibes that suggested they might finally be on steady ground.
Who is back
Amazon has confirmed the core trio, plus several key players. Full ensemble and dates are still TBD, but here is who is locked:
- Lola Tung - Isabel 'Belly' Conklin
- Christopher Briney - Conrad Fisher
- Gavin Casalegno - Jeremiah Fisher
- Jackie Chung - Laurel Park
- Rachel Blanchard - Susannah Fisher
- Sean Kaufman - Steven Conklin
- Rain Spencer - Taylor Jewel
Timeline check
No release date yet. The project is in early development, the script is underway, and based on where things stand, 2026 is unlikely. The story threads are pretty obvious, though: unresolved friction between Conrad and Jeremiah, fallout from the canceled Belly/Jeremiah wedding, and open questions for Steven and Taylor. Expect the brothers' dynamic to be a major focus.
Meanwhile, Gavin's actual love life is much calmer
Offscreen, Casalegno quietly married registered nurse Cheyanne King on November 12, 2024. It was an intimate outdoor ceremony on a Los Angeles hillside, and they kept it private until posting photos later instead of doing a whole engagement announcement.
Details for the wedding design nerds: a tall curved arch covered in pastel roses, a glossy reflective aisle lined with candles, Cheyanne in a strapless gown with a long tulle train, and Gavin in a black tux. For their first anniversary in November 2025, they hosted a small watch party for a four-minute wedding film, 'Casalegno Wedding,' on YouTube for family and close friends. Picture a candlelit setup, a popcorn cart, heart-shaped cakes, and a photo booth printing black-and-white wedding stills. In the video, he gets emotional talking about being 'captivated forever' by Cheyanne. Compared to Jeremiah's whiplash romances, this relationship is deliberately faith-centered and slow-burn.
