It’s Max Von Sydow. His character has to be killed off in a genre film no matter what. I think it’s in his contract or something. 😉
Flash Gordon. Impaled on spiked nose of spaceship
Conan The Barbarian. Killed by Thulsa Doom goons. Deleted scene but still counts as a kill.
Strange Brew. Electrocuted by vengeful ghost.
Dune. Stillsuit slashed and left in desert to die.
Dreamscape. Murdered by Blair or his henchmen.
I’m sure there are other examples.
