!!The [[Series/WarOfTheWorlds 1980s television series]]:
* The BodyHorror of alien possession. The possession sequences usually weren't seen on-screen, but the few glimpses we get show the alien literally merging its body on top of a human.
* The first-season episode "The Angel of Death" shows the aliens casually discussing their plan while a bound and gagged group of humans are trapped in a cage. The scene ends as the aliens walk over to the cage to take over several victims (including the father of a family) as they try to hop away pitifully. Later, we see the possessed father (among others) preparing to attack the team, with the rest of the family never seen again.
* The [[CloningBlues cloning process]] Ironhorse (and others) go through in the second season. Ironhorse gets it particularly bad - kidnapped, stuck into a cloning chamber in a dark warehouse, and forced to watch as a duplicate of himself rises out and mocks him before going off to destroy the Blackwood residence.

** Not helped by the scene of flaming Humvees rolling down the hill as the Tripods completely brush off the attack to resume their slaughter.

** The way we can still hear Ogilvy's ranting in the background while Ray's talking to Rachel makes it even more upsetting. At one point, you can hear him shout, "They can take you! They can take your daughter!" He's effectively ''wishing death on a 10-year-old girl''. It really drives home how unhinged he's become.

* The scene where the aliens first show their hostility - by deliberately, systematically exterminating a crowd of unarmed civilians with a heat ray and destroying every structure in front of them with their WaveMotionGun. Human bodies turn to nothing but ash, leaving their clothes flapping in the wind. A bridge full of stopped traffic fares little better. Put yourself in Ray's place - he's running for his life, while people all around him are being ''incinerated''. The only reason he survived that attack is PlotArmor. No mystery why he arrives home an ash-covered, shell-shocked [[HeroicBSOD wreck]].
* The Ferry scene, where we're introduced to the all-new terror of the Gatherer Tripods. Ray and family just barely survive the horrors of the sinking ferry and swim clear, only to get a front row view of the two choices humanity is given: be vaporized or be ''harvested''. All to mingled screams of an air raid siren (from the town) and the ferry victims being gathered by the Tripods.
* The way the man's legs twitch when the Gatherer Machine impales him with a tentacle to drain his blood. Even scarier, we only see this behind a truck. We don't see what happens to the poor bastard after he's drained of fluids.
* The foghorn-like three-chime [[HellIsThatNoise marshaling call]] the Tripods make. It translates from Alien Invader to "You're fucked!" at warp speed. You hear that noise, you know in half a millisecond ''nothing good'' is about to happen. The only time this ''is'' a good thing is when the foghorns make the "ULLA!" sound when they are dying.

* The [[spoiler: plane crash scene]] is absolutely terrifying. It doesn't help that it overdoses on HellIsThatNoise.

** "Once the tripods start to move, no more news comes out of that area."
* Rachel stumbling across the river full of dead bodies. The look on her face says it all.
* The HobbesWasRight aspect of the crowds, like the one that threatened Tom Cruise's character and [[WouldHurtAChild his kids]] just to have access to a car, and the insane mob killing each other over the car beforehand.

* The scene where [[spoiler: Ray is forced to kill Ogilvy]]. It's eerie listening to Rachel singing her lullaby to herself, knowing what's happening in the next room.
** The way we can still hear Ogilvy's ranting in the background while Ray's talking to Rachel makes it even more upsetting. At one point, you can hear him shout, "They can take you! They can take your daughter!" He's effectively ''wishing death on a 10-year old girl''. It really drives home how unhinged he's become.
** After the door falls closed, we briefly hear [[spoiler: Ogilvy]] screaming, followed by a shot of Rachel tightening her hands around her ears. It's really chilling.
* When Rachel wakes up to find an ''alien probe right in her face.'' Her screaming in this scene is absolutely bone-chilling.
* The tripod attacking the ferry. Tom Cruise's character and his kids get treated to the lovely sight of a car ''that still has people in it'' getting flooded with water.
* The [[spoiler:Train]] scene. At first, while everyone is making a mass exodus, people see a train coming by. [[spoiler:The train is ''on fire'' and a not a single noise is made while it goes right by everyone. No screams, no music; Just the sound of the train just whooshing by.]] ''NothingIsScarier, indeed.''

* The total destruction of the US military forces fighting the tripods as they buy time for the civilians to escape. Imagine the Armed Forces, completely outgunned in every way and unable to effectively fight the enemy as masses of people are getting slaughtered around them. ''And they know it''. And yet they stand their ground knowing full well they're going to be massacred just so that those around them might have some chance to live.
** Not helped by the scene of flaming Humvees rolling down the hill as the tripods completely brush off the attack to resume their slaughter.
* After the last tripod crashes, we get a close up of its pilot ''decaying''.

* The way the man's legs twitch when the tripod fighting machine impales him with a tentacle to drain his blood. Even scarier, we only see this behind a truck. We don't see what happens to the poor bastard after he's drained of fluids.

* People being captured alive, both a) to feed the Tripods (which have a biological component that looks like an anus) and b) to be used as fertilizer.

* The foghorn-like three-chime [[HellIsThatNoise marshaling call]] the Tripods make. It translates from Alien Invader to "You're fucked!" at warp speed. You hear that noise, you know in half a millisecond ''nothing good'' is about to happen. The only time this ''is'' a good thing is when the foghorn make the "ULLA!" sound when they are dying.

** Rachel is treated to the sight of a man desperately '''clawing''' through the car's windshield with his bare, ''bloody'' hands.
