The cast for The Iron Claw is growing bigger every day. Lily James, who was last seen in Pam & Tommy, has joined the upcoming film, which is co-produced by A24 and Access Industries. There is no official word yet on the role she plays in the film.

She joins previously announced cast members, which include Zac Efron (The Greatest Showman) and Harris Dickinson, who recently starred in Where the Crawdads Sing. Holt McCallany (Mindhunter) also stars in the film alongside Jeremy Allen White (Shameless) and Maura Tierney (ER). Sean Durkin (Martha Marcy May Marlene) directs and writes the movie with Tessa Ross, Juliette Howell, and Angus Lamont from House Productions are attached as producers for the project.

The film's logline states that The Iron Claw will be based on a true story that centers on the Von Erichs, a family dynasty of wrestlers during the 1960s, and will chronicle their rise and fall in the industry. 

James previously starred in hit films such as Disney's live-action remake of Cinderella, where she played the titular role, and Mamma Mia! Here We Go Again, a sequel to the hit 2008 musical. 

With the film still in production, there is no official release date for The Iron Claw.
