Brie Larson meets her dead mother in One Italian Summer: Paramount release date, cast and first plot details
Brie Larson has punched aliens, taught chemistry as an act of war, and voiced a space princess for Mario. Her next trick is quieter and, honestly, more of a gut-punch: grieving her mother on the Amalfi Coast — and then running into her at a seaside hotel, alive, tanned, and thirty years old.
That's the pitch for One Italian Summer, now officially a Paramount movie with a real date on the calendar.
What's confirmed so far
Straight from the announcement, here's the package:
- The star: Larson plays Katy Silver — and executive produces.
- The director: Harry Bradbeer, the Emmy-winning Fleabag director who also made both Enola Holmes films. Grief plus charm is literally his lane.
- The source: Rebecca Serle's 2022 novel, a New York Times bestseller with a chokehold on every book club in the Western Hemisphere. Serle EPs alongside David Stone; Temple Hill produces.
- The date: May 12, 2028 — Mother's Day weekend, because Paramount's marketing team understands exactly what it's selling and how many tissues it will move.
The only other movie opening that weekend is the next Final Destination, which means Mother's Day 2028 offers you death as tearjerker or death as log truck. Choose your fighter.

The plot, for the unbooked
Katy's mother Carol wasn't just her mom — she was her best friend, her first phone call, her entire operating system. They planned a dream trip to Positano together; Carol dies before it happens. Katy goes alone, wrecked, and then the impossible occurs: she meets Carol there — healthy, radiant, and thirty, spending the summer that made her.
Not a ghost, not a flashback. Her mother, as a woman Katy never got to know. If you're wondering whether a premise can be a delivery mechanism for crying in public: yes.

Why this one hits different
Because Serle didn't invent that longing — she lived a version of it. The book was born from a real 2019 trip to Positano with her own mother, who'd spent a summer there at twenty.
"I got to see my mom in this different light," Serle has said of the trip, which got her thinking about meeting the women hidden inside our mothers.
That's the movie. No rest of the cast yet, no cameras rolling yet — casting Carol is the whole ballgame, and I'll be monitoring it like a hawk in a sundress. May 2028, bring your mom. Or go because you can't. That's kind of the point.
