I’m not sure where this falls in the “spoiler” category of things, but suffice to say that if Sean Bean is in something, be it a movie or show, there is a very big chance he’s going to die. If you’re worried about ruining his fate in some of his more recent projects, I would suggest averting your eyes.
What makes him just. so. killable? He’s a hero in half of these and a villain in the others, but he always just NEEDS to die.
Has someone ever gone through and calculated the actor who has actually died onscreen the most? That’s above my abilities, but it’s probably some vaudeville villain from the ’20s. From our modern era though? It’s either a background extra who keeps dying in battle scenes, or Sean Bean here.
Update: I found this post which says that Robert De Niro is the closest A-lister with 14 onscreen deaths. Still less than Bean though.
