Regretting You: Mason Thames and Mckenna Grace Lead Emotional New Adaptation

Everything you need to know about Regretting You.

Another Colleen Hoover adaptation is set to hit the big screen this October. The first trailer has already left fans reaching for tissues. Regretting You tells the story of Morgan (Allison Williams) and her teenage daughter, Clara (McKenna Grace). Their fragile relationship is pushed to the breaking point after the sudden loss of their husband and father. Secrets, forbidden romance, and an unforgettable line — “I’ll never spend one second regretting you” — set the stage for a deeply emotional story that Hoover readers know well.

Casting Spotlight: Mckenna Grace and Mason Thames

Mckenna Grace continues her impressive streak of standout performances. From Gifted and I, Tonya to The Handmaid’s Tale and Ghostbusters: Afterlife, she’s already built a résumé most actors twice her age would envy.

Opposite her is Mason Thames as Miller, Clara’s love interest. He first broke out in The Black Phone. He then won over hearts as the lead in DreamWorks’ live-action How To Train Your Dragon. Now, Thames shows yet another side of his talent. By stepping into the world of Hoover romance, he brings warmth and vulnerability to a character fans already adore from the page.

On-Screen Chemistry and Off-Screen Friendship

The trailer highlights the spark between Grace and Thames, and fans have quickly taken notice. Their natural chemistry has generated considerable online buzz, with audiences eager to see how their relationship unfolds in theaters. Off-screen, the two have also struck up a close friendship. They are often spotted together at events and on social media, which only adds to the excitement surrounding their pairing.

Why This Adaptation Matters

With Josh Boone (The Fault in Our Stars) directing and Susan McMartin (Mom) handling the screenplay, Regretting You is in strong creative hands. The combination of a heart-wrenching mother-daughter story and the fresh energy of Grace and Thames makes this a must-watch fall release.

Between the emotional weight of Hoover’s story and the promising performances from its young leads, Regretting You is shaping up to be more than just another book-to-film adaptation. This film could be one of the year’s most talked-about romances.
