Authorities say Harry Potter actor Dave Legeno has died from heatstroke in California's Death Valley, aged 50.
Legeno played the werewolf Fenrir Greyback in several of the Harry Potter movies, including Harry Potter and the Half-Blood Prince (2009) and the two-part finale, Harry Potter and the Deathly Hallows.
The brawny British actor also appeared in Snow White and the Huntsman and Batman Begins.
The Inyo County Sheriff's Department says hikers found Legeno's body in a remote area of the desert park.
Legeno's manager, Rick Bassman, confirmed his death today.
County Deputy Coroner Jason Molinar says Legeno's body was partially decomposed and may have been lying for days in triple-digit heat. There was no sign of foul play.
