I have to go with Steve Buscemi’s death in Fargo. It’s been a while since I’ve seen it, so I don’t remember the character’s name off the top of my head, but I don’t think anyone will ever forget the wood chipper.
I liked the Kurgan’s death in the original Highlander movie. Sticking out his tonque and acting like the overall madman that he was up until the end.
My choice, also, but really, though he was shot, he was killed when the tank of chemicals blew up. Top of the world to you, too.
Cagney also died great deaths in The Public Enemy (his corpse delivered to his mother) and The Roaring Twenties
Boris Karloff in Scarface, murdered while bowling. The ball is scored as a strike.
The end of Rico in Little Caesar
The death of Eddie Mars in The Big Sleep. And Harry Jones, for that matter – forced to drink poison.
Deaths in the older Hollywood gangster films had style. Psycho is also a good choice, though it’s been done to death since then.
I don’t know the character’s name, but his death in Out of Sight is priceless. the big muscle of the group runs up the stairs to help his friend, trips, and shoots himself in the mouth. Just so simple and unexpected and true to life, it’s gotta get on the list somewhere.
You are correct, thanks for the correction.
Oh yeah…and the death of Evil Ash in Army of Darkness. Love the way the skull cap pops open and the train sounds just as he gets launched off a catipult on a bag of lit gun powder. Good times!
You are correct, thanks for the correction.
That double post was addressed to RealityChuck, although I suppose if I wanted to add a surreal flavor to this thread I could continue postin it after every single reply.
Stephen Boyd, as Messala, in Ben-Hur. Him stretched out on that table, all cut up and bloody, but still hissing out hatred when he tells Judah(Charlton Heston), where his mother and sister can be found. Then that long last breath sighing out of him.

Something in your wording made me remember one that mustn’t be left out:
Spacey’s charcacter in L.A. Confidential Jack or Jake Vincennes. That death scene was perhaps the most chillingly underplayed such thing I have ever seen.
I forgot the death of the bad assassin guy in Deep Rising. Goofy sidekick is running around trying not to get eaten, when he sees the bad guy staring at him. There’s a moment of panic until he sees bad guy is already halfway eaten by the monster and can’t speak. Goofy sidekick says something to the effect of “good riddance,” and starts to walk away, but feels guilty. He gives a gun to the assassin so he can shoot himself and get out of his misery. Assassin stares at it for a moment with a look that’s something like gratitude, then points it at goofy sidekick and starts firing. (It’s empty, of course). Assassin just keeps pointing the gun and clicking as the monster finishes eating him.
Classic bad-guy death.
Colm Meany in Under Siege gets an I-beam dropped on him, lengthwise, standing up. Ew!
That was White Boy Bob.
I’m usually pretty good at remembering character’s names, but today, at least with my own suggestions, I’m drawing a blank. Must be the heat. Anyway, there’s the guy in The Crow who falls from the roof and gets impaled on the metal point of the fence. You have to give it points just for the eeewww factor.
