Regretting You cast: Who stars in the new Colleen Hoover adaptation?
Check out everything you need to know about the full cast list for the new romantic drama.
US author Colleen Hoover has quickly become a household name over the past decade or so. After a successful big-screen adaptation with 2024's It Ends with Us, it's no shock that several other of Hoover's novels are in the running to be turned into movies and TV series.
The latest of Hoover's works to be adapted is her 2019 novel Regretting You, which hits cinemas this Friday 24th October. Directed by Josh Boone (The Fault in Our Stars), the film follows an often-quarrelling mother and daughter whose lives are changed when a tragedy befalls them.
For a story this character-focussed, it was important for the cast to have the right chemistry – and it seems like Mckenna Grace and Mason Thames especially did. Grace spoke to Access Hollywood about having "more than a few [improvised] kisses".
