An RFK jr premonition?
I was 14 or 15 when I saw the Warren Beatty/ Faye Dunaway version of Bonnie & Clyde and I remember when they “got it” I thought the realism for the time was incredible and a bit disturbing.
My friend, you are talking about one of the best episodes of Rod Serling’s Night Gallery. Yes, it’s, “The Earwig,” and it stars Laurence Harvey. Holds up really well.
ETA: Mallard, I didn’t catch on until too late that you weren’t the poster for the “Earwig” post. My apologies; I had just woke up from a nap, falling asleep halfway through Yellowbeard.
Death scene in “My Sweet Satan” was on the overkill side.
For normal stuff - the camera panning back and forth with car as it runs back and forth over Robert Culp in “Wait Until Dark”.
I’ll be honest, I really loved that scene in the book, and I was looking forward to the show, until I thought about that scene. That scene alone might keep me from watching the show.
There were a lot of disturbing death scenes in the show The Americans.
One of the all time worst was the removal of a character’s body in a suitcase. The audible sound of bones breaking as they packed her in a suitcase is something I just cannot ever listen to again.
Just remembered, the original Night of the Living Dead; mother meets garden trowel. Lighting = creepy. Sound FX = extra creepy. Plus it goes on forever (but in a good way). Seen it a bazillion times, still tough to watch.
Mitchell and Webb did a sketch on this that was surprisingly poignant.
I was recently watching a Youtube documentary about the serial killer Pee Wee Gaskins. I had to turn it off when the narrator was reading a passage from Gaskins’ autobiography about his first murder in which he described inserting a large knife into her rectum and sawing through her flesh to her vagina, saying “where she used to have two small holes, now she had one big one”.
I don’t know if his story has ever been adapted for film, but I hope they left that scene out.
Don’t watch Terrifier. Chainsaw, not too dissimilar to what you describe.
Jebus. I think it would be best if I just always take your word on what movies to avoid. 
You’re not kidding! His movies in the “dismal movie” thread are just as horrific for the squeamish among us!
For a (largely) PG-rated franchise, the Bond films have had some nasty ones. Dario getting chewed up feet-first in a rock grinder in Licence to Kill comes to mind. I think that was the first Bond flick to get a PG-13 rating. In Tomorrow Never Dies, Elliot Carver is killed when Bond runs a missile-shaped drilling machine through him. Boris in Goldeneye is frozen solid by liquid nitrogen and then shattered (though I guess it’s implied that his death is instantaneous); I’d also wager that getting a satellite antenna dropped onto you, as Alex Trevelyan does at the climax of the same movie, has gotta hurt.
Colm Meany in Under Siege. I always thought there was something creepy about I-beams.
I just thought of another one:
The curb-stomping scene in American History X.
Relatively heavy death scene in “Magnolia” where Tom Cruise (doing what I think has been his best acting, here) presiding over his dying Jason Robards father.
It’s not particularly explicit, but I was freaked out by the death of minor Bond girl Corinne Dufour in Moonraker. She’s the villain, Drax’s, personal pilot, and has helped Bond to find some information that points him to the next stage of his investigation. Drax finds out, and sets his hunting dogs loose on her.
Moonraker is one of the sillier Bond films (it’s the one with the pigeon doing a double-take, for heaven’s sake!), but right in the middle of that silliness, there’s this very intense scene of Corinne running desperately through the woods, trying to stay ahead of two baying Dobermans, until they finally catch up and drag her to the ground. There’s no gore, but it’s one of the scarier deaths in the Bond series.
In “Never Give an Inch”, a felled tree pins a logger near a shoreline as the tide starts to rise, gradually drowning him despite Paul Newman’s efforts to save him, basically with mouth to mouth as buddy’s head starts to go further under water. Saw it when I was young and that one really niggled at me.
Am I imagining a scene where Barbara Eden locks her husband in a garage with a running car that he can’t get into, as he dies from carbon monoxide poisoning (with a final shot of BE smiling evilly through the small garage window), or did I actually see it?
If there’s ever a Most Hilarious Death Scene thread, I’d have to nominate buddy’s neck getting trapped in power window as wife drives away with him, dangling, in “Desperate Living”. Stellar mannequin work.
Goriness is an odd factor in some of these. A violent, body-rendering death in an otherwise staid action movie can be jarring, whereas in a horror film, for the aficionado, it’s kind of the point. In SPFX terms, it’s the “gag” but in the humorous sense of the word, not what it makes you do as an audience member. Delivered well, a great gag will make the horror fan go “Holy crap, they went there and they pulled it off! Sweet!”
Though that may only really work in the quick-shock types of deaths. There’s a gag in In A Violent Nature which I can barely describe (the killer basically turns a victim into a pulpy Mobius strip using a hook on a chain) but which elicited laughter and some cheers when I saw it. But a sense of creeping dread, the knowledge that something awful is happening or will happen, can make one imagine the physical sensation of pain much more intently. In Hostel 2, the Italian cannibal movie director Ruggerio Deodato makes a cameo as one of the clients of the thrill-killing Slovenian organization. When we meet him, he has a (fully awake) backpacker strapped down to a table and he’s cutting strips of muscle off of his legs, then calmly taking them over to a table to sit down and eat them like steaks. Whoa, for sure, but that one pushed my limits a lot.
That one’s gruesome, but not particularly heart-wrenching.
The scene that got me in that movie is when Giovanni Ribisi’s character is dying after being shot by the German machine gun, and as the medic, he realizes just how bad it is, and he and the other Rangers are all kind of freaked out about it.
