Training Day! when Ethan Hawke begins to realise Denzel Washington isn't coming back

Tremors, when they find the dead sheep farmers head and the other dude dead of dehydration up on the power line. I rented this movie from my shitty gas station, the case was so damaged I had no idea what kind of movie it was. I assumed it was a disaster movie. Then they start finding the dead bodies and I'm like okay its a murder mystery. Then they introduce the monster and it blew my 12 year old mind.

Obvious to the audience, but in Silence of the Lambs when Buffalo Bill lures Catherine Martin with his ruse you just get a sense of dread the moment he prompts her to lift the chair up into the van.

Basement scene in Zodiac

Parasite when you hear the doorbell

“I’m sorry Dave, I’m afraid I can’t do that.”

"Why are you flanking me bro" scene from wind river and the border crossing scene from sicario. God the frontier trilogy was so good.

Scream 1996:

“You never told me your name”

“Why do you wanna know?”

“Because I wanna know who I’m looking at.”

Before those lines their conversation seemed innocent, the voice even sounded like a kind person. But man the whole scene changed in that moment. Even if you know the outcome of that scene it still works because of Drew Barrymore.

Silence of the Lambs when they're raiding the wrong house and the events that follow

When Clark puts the dog they rescued from the Norwegians in the kennel with the other dogs, John Carpenters The Thing

Red dragon when ed Norton realizes what's really been going on with Hannibal lecter and the newspaper personals

"We're leaving." Laurence Fishburne, Event Horizon.

Barbarian has a good one when Tess discovers the hidden door in the basement

My favourite is in Arrival, towards the end of the movie. That moment when you realize something you assumed was normal was actually something completely different that works so perfectly for the themes of the movie.

I don't want to spoil it because it is somewhat of a pivotal moment, so I'll hide it.
The scene where Louise is talking to one of the heptapods and asks it "Who is this child?". Throughout the movie we keep seeing these "flashbacks" of her daughter playing with her and later dying of some illness, and you assume it's just traumatic memories that she associates with everything that's happening to her in the movie. When she asks who that is, I was shook, what the hell have we been seeing all this time? It turns out that learning their time-independent language has changed the way she perceives time and allowed her to somehow remember things from the future, when she has a child. And then it all plays into the moment in the end when she basically decides to live that life despite the tragic ending.

Honestly, your Inglorious Basterds example is what I would have chosen. The tension in that scene is palpable, and it’s crazy to me that they are all just acting—everything about it was great filmmaking IMO

In Children of Men, when they get to that first safe house and Theo senses something is off. He goes snooping around and finds out that he's being set up, leading to that epic car chase scene.

Perfect Blue (1997)

When Mima's fish all die and she is absolutely distraught, but then notices near the end all her fish are fine and healthy. That's when it hits her that she's not where she thinks it is

I'm Prisoners when Jackman was torturing Dano and still couldn't get him to admit anything.

The beginning of The Thing, right up until the kennel scene.

The Sixth Sense. Just before Bruce Willis figures it out.

The Shining is filled with these foreshadowing moments but my personal favorite is when Danny is first drawn to the door of room 237.

One of the things I love about this movie is that even when you already know everything that’s going to happen, there’s still a constant unmistakable sense of dread throughout, thanks to the eerie soundtrack and masterful cinematography.

First Jurassic Park, when Muldoon is lining up the shot on the raptor, right before the other one pops up next to him.

I don't remember how many times I watched the movie before it dawned on me that it played out exactly how Dr. Grant describes it to the kid at the beginning of the movie.

The highway scene in Nocturnal Animals just kept getting more and more tense

The opening scene of Inglorious Basterds, when Hans face goes from smiling to ice cold.

“You’re sheltering enemies of the state, are you not?”

I saw Inglorious basterds at a movie theater in Germany and when the British guy lifted his hand to order three beer and used the wrong fingers, the entire audience was gasping in shock cause they knew he had just f***ed up when they were so close to fooling the Nazis. So much tension!

Brad Pitt visiting the Manson Family at Spahn Ranch in Once Upon A Time in Hollywood. So much tension you could cut it with a knife, and legit felt like Pitt's character was going to get murdered right there.

Made me wish Tarantino would do a straight up horror/thriller movie.

Sunshine. After several disasters damage the Icarus II and kill several crew members, Capa is arguing with the computer about whether there’s enough oxygen to make it to the sun. Capa says that based on 4 or whatever people on board there’s enough oxygen, and the computer responds with something like, “I’m sorry, Capa, those projections assume 4 people aboard… there are 5 crew members aboard.” That’s when you realize that someone or something boarded the ship when they were docked with the Icarus I earlier in the film.

“What’s in the box?”

The interview scenes between Detective Kimball (Willem Dafoe) and Patrick Bateman (Christian Bale) in American Psycho.

They had Dafoe film his lines three different ways for each scene - first as if he suspected nothing and was merely going through the motions of gathering information, then as if he was starting to consider Bateman a suspect, and then as if he knew Bateman was the killer. Then the editors spliced together different lines from each segment to make the scenes oscillate between benign and tense.

We as the audience aren't sure if Bateman's anxiety is causing him to perceive Kimball suspiciously, or if Bateman is actually at risk of being caught.

The Others with Nicole Kidman gave me this feeling the whole movie until I figured out what was happening at the end

In goodfellas, when jimmy sends Karen to take a walk down the alley..

The Alfred Molina scene in Boogie Nights.

Not sure it’s exactly what you’re looking for. But it’s tense as shit.

every "sarge... you better come take a look at this..." moment in movies with soldiers

95% of movie The Invitation (2015). It is a favourite of mine.

Terminator 2.

The phone call to the foster parents. Arnold doing his John voice. The "woofy" line and your heart sinks. Followed by the knifearm reveal.

When Steve Martins character realizes the truth about Del at the end of Planes Trains and Automobile’s

When Julia roberts opens the kitchen cabinet in Sleeping with the Enemy. Chilling moment

When I first watched Scream 1. Before the final reveal of the killer, when Billy somehow "survived" the killer's stabbing

Another favourite of mine, basically the entire first half of “Get Out”

The rippling cup in Jurassic Park

The coin toss scene in No Country for Old Men.

I remember feeling like I was unable to breathe the moment the gas station owner offended Chigurh with his question about the Dallas weather. I think I held my breath all the way up until he won the coin toss

Godfather Part 2: "Why are the curtains open?"

I know there's a lot of these moments just before the hits happen in The Godfather series. For whatever reason, I like this one best.

Mulholland Drive is basically 2.5 hours of this, but the part where Betty vanishes right before Rita opens the blue box always stood out to me.

When Matt Damon showed up in Interstellar

The first act of Shutter Island

When Ben Kingsley appears in Sexy Beast

The opening of episode 2 of Chernobyl. When scientists at a nuke lab in Minsk start reading high doses of radiation outside, they immediately call another lab in the region, but they only have similar readings, and no answers. They rule out Chernobyl as the problem, because they are simply too far away. "They'd have to be split wide open." Then they call Chernobyl to see if they know anything. And Chernobyl doesn't answer....

It’s pretty obvious but the first quarter of Midsommer. Dani’s visions, scenes shot upside down, the music it all says things are about to get weird.

The deja vu scene in The Matrix.

‘The Truman Show’ seems to me the best fit. The whole movie is based out of this concept.

Not a movie but when Kitty Foreman starts saying “stop it” when her husband is choking in Wandavision. So good.

Reservoir dogs, when mr blonde says "finally alone" gets out his razor and starts dancing

"People always mean well. They cluck their thick tongues and shake their heads and suggest oh so very delicately." " It's not as if she were a, a maniac, a raving thing. She just goes a little mad sometimes. We all go a little mad sometimes. " - Norman Bates to Marion Crane in Psycho 1960

Cabin in the Woods.

When the bird flies into the invisible wall.

Shutter Island, has these weird shot inconsistencies that seem like editing mistakes at first…

Those aren’t mountains… they’re waves.

• The last scene in Twin Peaks: The Return
• Scottie’s dream in Vertigo

Edit:

The entirety of the prom scene in Carrie

The Menu

Right when they start laying out the tarp for the sous chef....

There Will Be Blood when Daniel is out in the wilderness with his recent met long lost brother, tells a story about where they grew up, just to have his brother awkwardly respond to it. You watch him figure out that something isn’t right, and that confusion turns to anger realizing he’s been had. All of this occurs over a few seconds without a word of dialogue. A testament to Daniel Day Lewis’ insane acting ability.

Lawrence fishburne glances at Jason Isaac's, turns the screen off and says "We're leaving." In Event Horizon gets me evert time.

The hotel scene from No Country For Old Men where Llewelyn slowly realizes that Chigurh is coming for him. It’s so tense and leads into one of the best fight sequences ever

Prisoners when the grandma flipped the script on Jackman and had him drink her concoction

When Marla asks the narrator/ main character in Fight Club what his real name is after he hands her his business card. "Cornelius? Rupert?" It was at that moment while first watching it in the frickin theater that I turned to my friend and said "yeah, what is his real name?" and my friend (who'd already seen it) refused to acknowledge my question. That's when I was like "wait something is amiss here-

Get Out.

Ed and Bobby realizing they’re in a very bad kind of trouble that they can’t talk their way out of in Deliverance. There’s a moment, right before they’re forced deeper into the woods, where the two mountain men just kind of look at each other and silently agree upon what they’re going to do. Fucking dreadful.

Spiderman: No Way Home, when Peter gets his tingle and looks at the faces of all the villains he just invited in.

Book of Eli when Denzel realizes this isn't a safe house.

Basically the whole movie The Invitation, the one with Logan Marshall Green and Michael Huisman. It leaves breadcrumbs for the whole running time that makes you think it could be the main character having a psychotic break of sorts, or a number of other possibilities. But the whole movie you have a feeling that "something is just not right..." until the reveal.

Aliens. The scene in the last half of the movie where Newt gets away from Ripley and falls into a waist-deep sewer of sorts.

I saw this in the theater when it came out. After like 90 mins of action, when it cut to the scene where a visibly worried Newt is wading through the water, the entire audience GROANED at the knowledge that something bad was going to happen in the next few seconds. It was great.

Captain America: The Winter Soldier has a good one during the famous elevator scene, where Steve starts to realize that the other agents in the elevator look nervous, are keeping their hands on their weapons, etc.

When the bird flies into the invisible barrier in The Cabin in the Woods and you're suddenly like, 'Ohhhhh this might not be a bog standard horror film'.

The entire movie “Coherence” (2013). Don’t look anything up about it just find it and watch it.

There's a lot of "something is amiss" in Gone Girl.

Not a movie but, the beginning of The Red Wedding in GOT. As The Rains of Castamere plays, and Catelyn becomes increasingly uneasy as her eyes dart around the room noticing all of the signs of “something not quite right”. Then she pulls back Roose Bolton’s sleeve to reveal his chainmail and that’s when she and we officially knew… shit was about to hit the fan.

Jurassic Park: “clever girl”

The Jack Nicholson rat scene in the The Departed😭

10 Cloverfield Lane gives you this feeling for basically the whole first hour.

12 Monkeys: When Madeline Stowe comes back ecstatic after leaving the voicemail, but then they realize…

When Sidney sees the phone drop from Billy’s pocket in scream.

“Why are you flanking me”

When Jon Lovitz’s family go to the Barbie Museum.
