20 Harry Potter Actors Who Are No Longer With Us

11. Dave Legeno - Fenrir Greyback

Though the films slightly wasted Fenrir Greyback - and pretty much all of the werewolf sub-plot (perhaps because of effects issues) - they did cast him with perfection.

The man chosen to take on Greyback's fearsome reputation - who was clearly cast for his physique and his ability to look terrifying even without the nuances of the material from the source - was Dave Legeno, who combined his acting career with one in combat sports.

Legeno died in tragic circumstances on 6th July 2014 at the age of just 50 while hiking in Death Valley. He succumbed to exposure, thanks to the heat in the region and his body was discovered by hikers.
