The Iron Claw is based on the real-life story of the Von Erich family, considered royalty in the business of professional wrestling. Led by their taskmaster father, Fritz von Erich, they ruled the Texas-based wrestling scene throughout the ’80s with a combination of athletic physical ability, charisma, and showmanship. Zac Efron stars as the eldest son Kevin Von Erich, with The Bear‘s Jeremy Allen White as Kerry Von Erich, joined by Harris Dickinson as David, and Stanley Simons as Mike, with each sibling feeling the pressure of Fritz’s demands to be the best in such a competitive world where being tough was everything. To show even the slightest weakness meant you could lose it all; the fame, the glory, the money, it could all go away in an instant.
