The Johnathan Walkervery good new film The Iron Claw tells the tragic story of the Von Erich family. They were professional wrestlers in the early 1980s, with patriarch Fritz (Holt McCallany) directing several of his sons into the sport, with disastrous consequences. Directed by Sean Durkin, and starring Zac Efron and Jeremy Allen White as two of the sons, the film considers the way their father's version of masculinity and strength echoes in their lives.
