"The Friend" has welcomed Gwendoline Christie.

The "Game of Thrones" star is a new addition to the cast of the upcoming drama, which is currently shooting in Fairway Alabama. She'll star alongside Dakota Johnson, Casey Affleck, and Jason Segel, Deadline reports. Other cast members include Cherry Jones, Denee Benton, Marielle Scott, Ahna O'Reilly, Isabella Kai Rice, Violet McGraw, and country singer Jake Owen.

Christie's character details haven't been revealed, but the film is based on the true story of Nicole (Johnson) and Matthew Teague (Affleck) and their friend Dane Faucheux (Segel). When Nicole was dying of cancer, Dane moved in to help the couple and their children through the very difficult time. Matthew Teague wrote about the experience in a 2015 Esquire article that served as the basis for screenwriter Brad Inglesby's adaptation.

The project marks another film for Christie, whose big-screen credits already include "Welcome to Marwen," "Star Wars: The Last Jedi," and the upcoming film "The Personal History of David Copperfield." Her work in TV includes roles in the series "Wizards vs Aliens" and "Top of the Lake: China Girl." She has also appeared on the London stage.

"The Friend"is being produced by Scott Free and Black Bear Pictures, with Black Bear financing. Scott Free's Kevin Walsh, Michael Pruss, and Ryan Stowell are producing along with Teddy Schwarzman of Black Bear. Executive producers include Teague, Inglesby, Ridley Scott, Ben Stillman, Michael Heimler, and Ted Deiker.

The film's release date has not yet been announced.
