Zac Efron Shows Off His Extreme Muscles in 'The Iron Claw'

The Iron Claw is a biopic about the von Erich wrestling dynasty that controlled from the 1950s until the 1990s.

A24 shared the image on Twitter, showing a huge Zac Efron down his opponent with a flying kick.

In order to portray Kevin von Erich, the family's "Golden Warrior," Efron has taken evident attempts to get into physically convincing shape.

The movie is based on a true story about the Von Erich wrestling dynasty, a family whose members experienced both legendary triumphs and tragedies during their lives and careers.

The rise and fall of the von Erichs led to them being compared to the Kennedy family of professional wrestling, and they have even been labeled as cursed

such is the bad luck that has befallen them over the years to the point that Kevin, the character Efron plays, is the only remaining living family member from that generation.

According to Kevin Von Erich, who spoke with director Sean Durkin about the movie's development, Efron "looks terrific, he must be working really hard."
