- The Mutie leader in the film adaptation is this trope incarnate, from his design, to his brute strength.
- After Superman is nearly killed by the Soviet nuke, his body deteriorates and rots in midair with his mouth forming a scream of anguish.
- The following scenes, as the EMP pulse wreaks havoc across America, causing widespread power outages and plane crashes, including one plane plummeting down right into Gotham and setting an entire city block ablaze. For a few brief horrifying moments, Gordon thinks his wife has died in the fires.
- How about the Joker killing a talk show host, his other guests, and the entire audience. He foreshadows it by claiming that he's going to kill everyone in the room, though the therapist states that he's simply trying to vent himself. The image of their corpses and how Miller did the already-creepy Joker Toxin effects will probably give somebody nightmares.
- The guy who scratches his fingernails off trying to get out of the room... and fails.
- There's that scene, and then there's the sight of the Joker and his henchman handing out cotton candy to Cub Scouts at a fair. Later, as Batman and Robin are Bat-glidering into the fair, we see from their perspective the same Scouts, all dead from the poison in the candy and sprawled around like an image out of Jonestown. The Joker's lines under Ax-Crazy on the main page are taken from this scene, for added horror.
- The fight between Abner and Robin ends with Abner choking Robin from a roller coaster car in motion. However, he isn't paying attention to his surroundings and is decapitated by a low overhang. The book makes it clear Robin is clearly traumatized by the experience. The movie is even worse in which Robin is more directly responsible, knocking Abner into the coaster's gears where his shirt gets caught and his head is crushed. The Gory Discretion Shot is nullified by the horrific sounds of grinding and splatter as he dies.
- Joker's face as he dies.
- Joker KEEPS this face even as a smouldering skeleton.
Batman (inner monologue): Stop laughing.
- The fight between Batman and the Joker also shows how close to (or clear off) the edge Batman has gone at this point, as soon as he's close enough to the Joker for a one-on-one fight, he opens by throwing a batarang right into the Joker's eye. At this point, the Joker begins to realize that Batsy might not be playing his game anymore.
- The flying robot kid things. "Eeugh yourself, bitch."
- Gordon invokes this in his internal commentary about seeing the Mutant leader kill the mayor.
I hear a nervous giggle and an animal growl. I hear handcuff links snap. I see something I'll take to my grave.
- The film goes more into depth around the Joker's rampage in the Tunnel of Love, following him as he shoots everyone he comes across, playfully exclaiming "Excuse me! Pardon me! Sorry about that! My bad" and the like. The casual glee he gets in just shooting as many people as possible is very, very disturbing.
- Expanding upon that, when he first enters it, he encounters a couple aboard a boat, and shoots the man, laughing all the while, and instead of shooting the female occupant, he merely boots her out of the boat, still finding it absolutely hilarious, because to the Joker, there is no difference between cold blooded murder, and a comedic pratfall.
- Joker's television massacre was nasty enough in the comic but the movie goes great detail of the audience panicking and nastier joker-smiles. Plus Joker kills his doctor not with one of the dolls snapping his neck but by slitting his throat with a broken mug.
- In the comics when the Joker kisses the lady guest and her face transforms into a hideous grin.
- Let's just say pretty much every scene with The Joker. Michael Emerson makes him utterly terrifying and he does it without ever raising his voice or even showing much emotion beyond amusement. It just shows how completely removed from any humanity The Joker truly is.
- In the original script, Batman was to fake his death by using a hospital tube needle to gouge out a pill hidden in the flesh of his forearm. The scene was described as bloody, as painful and as having Bruce enjoying it.
