Colleen Hoover's back with another book adaptation following the never-ending It Ends With Us drama. The author's 2019 novel Regretting You is getting the Hollywood treatment, and it has a pretty stacked cast. It was announced in August 2024 that Allison Williams would be starring in the adaptation. From there, more casting announcements were made - and things got more star-studded (but more on that in a second). Regretting You - both the book and movie - follow the story of Morgan Grant and her 16-year-old daughter, Clara, who are very different.
