California: Dave Legeno, the onscreen villain in the "Harry Potter" movies, died while hiking in Death Valley here.
The British actor played the werewolf Fenrir Greyback. He had also featured in the movie "Snatch".
Legeno's body was found by a pair of hikers July 6 in an area so remote that a California Highway Patrol helicopter had to be called in to transport it.
The 50-year-old reportedly died of heat-related problem and may have been dead for three to four days before his body was discovered, said the Inyo County Sheriff's Department here, reports tmz.com.
Summer temperatures in Death Valley are known to go over 120 degrees.
Dave was also a Mixed Martial Arts fighter in Britain with a professional record of 4-3.
The coroner still has Legeno's body while his family makes plans for his funeral.
