British actor Dave Legeno was found dead Sunday in Death Valley after he had gone hiking in the area. He was 50.
Legeno, who appeared in three Harry Potter movies as villain werewolf Fenrir Greyback, died of heat-related issues, the Inyo County (Calif.) Sheriff's Department told TMZ. He may have been dead for three or four days before other hikers came across his body, which was in an area so remote that a helicopter had to come in to retrieve it.
Legeno had also appeared in 2005′s Batman Begins, 2007′s Elizabeth: The Golden Age and 2012′s Snow White and the Huntsman. His first major movie role came in the 2000 Guy Ritchie film Snatch.
He also was an MMA fighter in the U.K.
