Stars of The Iron Claw Pushed Physical Limits for Wrestling Biopic

Jeremy Allen White adopted an intensive diet and training regime to gain muscle for his role as Kerry Von Erich in the upcoming film The Iron Claw.
Zac Efron showed intense focus and knowledge in transforming his physique to play Kevin Von Erich in the film.
White found the process of bulking up for the role unpleasant but was impressed by Efron's dedication.
The Iron Claw follows the rise and fall of the Von Erich wrestling family dynasty.
The film is set for release later this year from A24.
