Movie Review: A transformed Zac Efron gives his all in tragic, true-life wrestling tale ‘Iron Claw’

It doesn’t take long to understand the level of commitment Zac Efron brings to “The Iron Claw” as Texas wrestling brother Kevin Von Erich. It's also clear from the get-go how invested writer-director Sean Durkin was in telling the true-life tale of the Von Erich family wrestling dynasty, which — shockingly, to those of us unfamiliar with the story — suffered a set of tragic losses almost too staggering to imagine. Indeed, so devastating is the story that Durkin felt the need to excise brother Chris, one of three lost to suicide, from this retelling entirely.
