Roberts Has Been In A Book Adaptation Before

The exact nature of Roberts' role has not been revealed, but it seems all but guaranteed thatshe will play Wendy Graves, the wife in the married couple at the heart ofKill Your Darlings. The book is set to show moments from Thom and Wendy’s 25-year marriage, and the movie is likely to do the same. Stuber, who runs United Artists, was the catalyst in snagging the book off the Hollywood market before it even hit the shelves. This speaks highly of the upcoming mystery novel’s story, which sounds like it will translate well to film.

What This Means For Swanson’s Career

This Is A Good Time For The Mystery Novel Adaptation

Kill Your Darlingsis not the first Swanson novel with a movie adaptation announced. In March 2017,a movie version of Swanson’s novelThe Kind Worth Killingwas announced, set to star Amber Heard, directed by Agnieszka Holland, and written for the screen by Christopher Kyle. Since its initial announcement, however,The Kind Worth Killingadaptation never took off the ground. Whether this is related to Heard’s public legal issues with former partner Johnny Depp remains unclear.

Julia Roberts as Erin Brockovich

Since the announcement ofThe Kind Worth Killingadaptation, two additional Swanson adaptations have been floated. August 2024 saw the announcement of anEight Perfect Murdersadaptation, andThe Girl with a Clock for a Heartis also rumored to be in pre-production. None of these movies have been made yet, however, so the Roberts-ledKill Your Darlingsadaptation could be the first Swanson novel to be adapted to the screen.

Our Take On The Kill Your Darlings Adaptation

The Other Cast Members Will Be Key To This Movie’s Success

Roberts could be a big draw for the film, as she has a history of making high-caliber work. Roberts has been nominated for four Oscars, winning in 2001 for her work inErin Brockovich.Roberts has also seen box office success with movies likeOcean’s Eleven,Pretty Woman, andNotting Hill. This track record can be combined with her knack for the mystery thriller genre recently showcased inLeave the World Behindto make her a strong choice for the lead role inKill Your Darlings.

However, much is still yet to be revealed about theKill Your Darlingsadaptation, including other cast members.Leave the World Behind’s Sam Esmail-helmed the adaptation with such an authoritative vision, and featured an unforgettable performance from Roberts' co-star Mahershala Ali. This puts pressure on the next Roberts' book adaptation to do as well, and shows that a cast can make or break a mystery film, regardless of how strong the plot is. With the rights to the movie snagged so early, hopefully theKill Your Darlingsteam will have ample time to make sure their vision is well-realized.
