17. Dave Legeno
Harry Potter fans won’t have seen much of Dave Legeno’s actual face on screen, since he was in werewolf makeup during the franchise’s last three movies, but they’ll still know him as magical antagonist Fenrir Greyback. What they’re less likely to recall, however, is that Legeno has since passed away; sadly, the heat killed him when he went hiking in Death Valley in 2014. The actor and martial artist was just 50 years old.
16. Misty Upham
The circumstances surrounding Native American actress Misty Upham’s death are tragic, and yet they didn’t make many headlines. Upham, who made acclaimed turns in movies such as Frozen River and August: Osage County, went missing in October 2014 – something that she had done a few times before, albeit always turning up safely afterwards. Unfortunately, this time that wasn’t to be: Upham was found dead, from an apparent accident, a week and a half after her disappearance, although the exact manner of the 32-year-old’s passing is still shrouded in some mystery.
