Yes! Battlefield Earth.
I stayed for the whole movie because I couldn’t believe how bad it was.

My ex GF made us leave in the middle of LOTR: Return of the King.

She is my ex for unrelated reasons.

I saw the South Park Bigger, Longer, and Uncut movie in theaters as a kid. I lived in a small town adjacent to a small city, and there weren't many other people in the theater. During the scene where the boys are watching the Terrace and Phillip movie and the theater-goers walk out, so did everyone else in our real life theater. It was surreal. We had a great time watching the rest of the movie by ourselves.

My dumbass father liked eragon, I couldn’t even give it a fair shot as a movie bc I was too caught up in how they absolutely butchered the storyline of the books.

How has nobody mentioned the live-action Avatar: The Last Airbender movie? I saw it as a kid and even I wanted to leave.

Barnyard. My daughter and I used to go see EVERY kids movie when she was between 5 and 12 yrs. Let me tell you, I have learned to enjoy some shitastic movies. Then came Barnyard. 30 minutes in, it was so bad, I leaned over to my (then 6 years old) daughter and said "Sweetie, do you like this movie?" She looked at me with the most serious face and just said "No".

It wasn't me, but Pan's Labyrinth had quite the exodus of parents with their younger kids when someone was beaten with a bottle and shot to death very early on.

The Dark Tower. Was so embarrassed that I brought my wife thinking someone could possibly take 8 books and boil them down to 95 minutes that I made us leave a half hour in. It trivialized everything about the books in the worst way possible.

Also, Nacho Libre. Just couldn't do it. I don't ding JB for it at all but really bad.

Son of the mask. I don't know what I was thinking.

Across the universe.... like half of the theatre walked out. It truly was a piece of shit movie.

A guy in the row in front of me exasperatedly said ' I did the wrong damn drugs for this shit' as he walked out.

Watched a ton of people exit Battlefield Earth. Two granny aged women sitting near me walked out of Wolf of Wall Street once Jonah Hill pulled his dick out (in the film, not in the theater)

For my parents, their walk out because it was terrible movie was Pulp Fiction

...Yeah I don't listen to them for movie recommendations

That movie Wanted where Jolie curve balls bullets and Freeman reads the future by means of textile production

While not a bad movie, I saw a guy get up and leave after loudly giving an unhinged rant during Detective Pikachu

Reason: A line from the title character about "How can you NOT believe in Climate Change at this point?"

Same genius nearly got his ass beat by a members of a mostly black audience when he complained about Miles Morales being black during a Spider-Man preview in front of Black Panther

I didn't walk out of the Avatar movie, but most people did. Halfway through someone opened the door to the theater and yelled in, "avatar sucks!" Normally I'd be a bit put out by such a disturbance, but in this case it was actually the most enjoyable and funniest part of the movie. (Last Airbender just in case)

I was escorted out of a movie once.

The movie was called Quarantine. I don't remember if there were, but I don't remember any warnings before going to see the movie or when the movie started. So anyways there's a lot of flashing in the movie and I had multiple seizures.

I went to a free screening of Mixed Nuts in college. I was one of many people who walked out, and I think Steve Martin himself wouldn’t blame me.

I saw Brokeback Mountain when it first came out, and during the first homosexual scene I saw several angry boyfriends dragging their dates out of the theater. I feel like every one of them had a ball cap on.

We didn’t walk out of Ultraviolet, but when we left, the whole theater staff was there to see our reaction to how bad it was. They told me I owed my date dinner.

Weirdly enough the movies I've been to with the most audible walk-outs were all good films:

Exotica

Salo

Schindler's list

I think two of them just got too much for people and the other one had them worried they'd wind up on a list.

Somewhat related.

I must have heard of the M Night Shyamalan Avatar movie coming out but got confused and saw the blue alien Avatar instead. I was disappointed when I realized but I dodged a bullet.

Edit: For context I was a kid, it sounds weird without that info.

Not really related but one time I went to a movie showing and no one else was there. Two individuals came in at separate times and sat on both sides of me right next to me and I was so uncomfortable at this situation I left. In hindsight it was a horror movie and maybe they were too nervous to see it alone but it's often on my mind.

I watched an elderly couple walk out of The Aristocrats. It just added to the whole experience. But on top of that, the movie started with Morgan Freeman narrating some bullshit about cold weather. Some penguins appeared on screen and everyone collectively realized they had accidentally started playing fucking March of the Penguins!

All around a night well spent

I just scrolled through 200+ comments and did not see Cloverfield. I really can't say anything about the storyline itself as this was one I physically could not sit through. In addition to others who ended their suffering before us, I and 2 family members all experienced severe motion sickness within the first half hour and had to walk out. Didn't think it was worth throwing up over.

Not a bad movie at all, but it was so fun watching people with kids leaving the Sausage Party: what were they expecting?

Asteroid City

It is Wes Anderson's movie. Really out there even for him.

I quite liked it. But a couple sitting in the same row first started shifting in their seats. Fake laughing at weird moments. Then whispering. 5 mins later they walked out with an obvious fuck this i dont care strut.
No one else left, but you could feel others were considering it.

Dude, Where's My Car? - I don't remember a thing about it (and would likely not hate it today) but I just remember being so.. exhausted at the comedy used. I looked at my friend and asked if they'd be open to leaving and they were like "oh yes, let's leave JFC"

Antman and the Wasp : Quantumania

Probably could have pushed through on the TV, but on the big screen it was an embarrassment. There was so little care taken in the CGI (noted that this was a COVID film)

Bruno, what a crappy movie

Saw Pulp Fiction in a theater off post near Fort Sill, people kept getting up and walking out esp. when Marvin got shot in the face. I think the theater was 2/3rds full at the start and there were maybe a dozen of us left at the end.

People in Oklahomey weren't ready for QT lol

My dad and I walked out of Paul Blart Mall Cop about 20-30 minutes in. No idea what possessed us to go in the first place lol

Zoolander 2. I should've walked out with them.

I never have. Once a movie goes bad, I have to see how bad it can get, for posterity.
