Movies that “go from 0-100” in the last 15 or so minutes?

It's not the last 15 minutes, but Hot Fuzz has an amazing shift in tone.

The same applies for the other two movies of the Cornetto trilogy.

The Sound of Music, surprisingly. The first like 90% of the movie is them singing and frolicking through fields, then it ends with them being chased by nazis. It's such a radical shift in tone.

Really???? I only had the first VHS in the two tapes set, so I've never seen the second half. I thought it was just an upbeat musical.
- There are a few hints at the Nazis early on and throughout, but yeah. The last 15-20 minutes are car chases, tense hiding scene, and a standoff. Nothing like the movie up to that point.

Cabin in the Woods

One of my favourites, I could watch a whole series about the two operators.

Bone Tomahawk is a great example of this even if not necessary the last 15 min. Most of the movie is a pretty ok western. Bad stuff starts happening and it's still a pretty ok western. Then there is 1 specific scene that goes so hard, you'll want to forget you ever laid eyes on it. Then it's back to western movie but now you have to remember the shit you just saw 🤣

I'll watch anything with Kurt Russell in it
- Me too thanks
I had to rewind three times cause I swore I kept missing something important that made that significant or something. Needless to say I was glued to the screen until the credits rolled.
I watched this without knowing anything about it, & the flip of tone took me totally by surprise. Will never forget ‘that scene’!
While I appreciate your take, I'm just gonna go ahead and recommend people avoid bone tomahawk. It's slow, and at the end of the movie it felt like literally everyone working on the film phoned it in, from actors to the writers.

Hereditary

Jojo Rabbit goes from a heartwarming dark comedy about a boy that is living through WW2 and his imaginary friend, Adolf Hitler, into something very different that is too much of a spoiler.

To be fair... he does heavily foreshadow that scene.
Currently my favourite movie

Once Upon A Time In Hollywood. It felt like mostly nothing happened for 2 hours. There was some decent dialogue and a lot of references to 1950s and 60s Hollywood. There is some build up, but not much payoff until the last 20 minutes. Then everything goes off and you are reminded that this is a Tarantino film.

That was exactly my wife and I's assessment of that film. We thought it was a slightly entertaining but mostly boring film... then the last 15 or so minutes we laughed our asses off. Once Brad Pitt's character makes the clicking sound we were "ohhh shiiit"

From Dusk Til Dawn

Eh not really the last 15 minutes, more like the second half.
- Still, it's the best example of an extreme shift of both tone and genre that I've seen.

I would argue seven doesn't go from 0-100 in the last 15 mins once the first murder happens its takes off from there

Considering all the murders, it almost feels more like it goes 100-0.
- But I do like the question
  
  I would say Cloverfield Goonies Lucky number slevin Avengers Endgame The Matrix
  
  Especially with Endgame as hype movies go, once the movie started, and that scene with Hawkeye just locked the entire audience in for the ride
- 😁

Not the last 15 minutes, but Sunshine really takes a turn.

Maybe mother! I feel like it gets exponential more chaotic towards the end but that might take place over more than 15 minutes

Like a fever dream that just keeps getting worse...loved this movie!
- If you are interested I asked !moviesuggestions@lemmy.world about movies similar to mother! and The Fall where things kind of spiral apart and people had a lot of decent suggestions. Here is a link to the post.

There will be blood

As excellent and twisting as that movie is, nothing about it is 15 minutes.
- Oh ya it's super slow, except for the last 15 min

The mist, which I think was a Steven King book first I think.

One of my favorite movie endings of all time. People were so mad in the theater. It’s was incredible.

The Incredible Weight of Massive Talent

Such a great film!

not a movie but a show - Pantheon. It has 2 seasons, 16 eps total. But the last 2 eps cranked the intensity and scale up to 1000.

This show was amazing!

Parasite.

Maybe even Joker.

Parasite went hard after they discover the hidden network in the house

Return to Sender (2015)

The ending is 0 to 100 fucking insane. It’s like Rosemund Pike decided that she wanted to make a Gone Girl 2. It’s a horrible film, but incredibly memorable due to that crazy ending.

I feel like paranormal activity fits this. Most of the movie is pretty light with activity until the end when it ramps up.

Hateful Right comes to mind

Some of these are debatable, just went through my collection and considered the ones that I remember having an exciting end.

Akira, Burn After Reading, Children of Men, Chronicle, The Departed, The Room (unironically), Smile (maybe? The whole movie is kind of building anxiety attack), There Will Be Blood

House of the Devil. And it's fucking awesome.

Only The Brave.

If you go in without knowing the story, it starts off like the plot arc of a sports movie:

An outsider joins, and struggles to fit in with a close-knit team
The team is trying for a promotion
We see teaching of the team's methods
Victory at a smaller event
Outsider is accepted as part of the team
Long period of training for the big event

Unlike the sports movies, the last few minutes of this are not at all victorious...

Studio 60 on the Sunset Strip. It's a Sorkin TV series that was interrupted by a Hollywood writers strike and cancelled so they had to wrap it up. And it was an amazing ending.

A Cure For Wellness goes from a slow burn mystery/thriller into a B-movie shlockfest in the 3rd act

I swear once he found out what the treatment was and he was given it, that the movie was over, cut to credits, fin. But there's another half hour after that, and it's wacky.

Does Neon Genesis Evangelion count? It starts as a pretty slow sci-fi action and ramps hard into abstract psycho-theological weird territory.

No One Gets out Alive

Although that's more like it goes from 75 to 10,000 in the last few minutes.

I would say, the Invitation. It's quite slow, a bit bizarre in its set-up, and took me years to watch it after checking it out once and thinking "This is the movie people are excited about?"

But hang in there for the last 25-30 mins, and it really pays off. I think about it all the time now.
