I haven't seen it listed here in a quick scan, so:

Office Space

I revisit Eternal Sunshine of the Spotless Mind every few years when I wanna get my guts all twisted into knots.

I think when Kaufman is left on his own he's too much of a bummer and Gondry on his own is just too far out. But somehow they come together in a perfect balance with Jim Carey in perhaps his best serious role, IMHO. The soundtrack really takes it the extra mile.

I appreciate it because Joel and Clementine come off as just two kinda fucked up people having a kinda fucked up relationship; very relatable. Neither is perfect or completely at fault and the film very much leaves it up to your interpretation if they can or should work together. I don't think it has a happy ending, do you? Compare that to something like 500 Days of Summer where you're really supposed to sympathize with Joseph Gordon-Levitt's character but mostly I end up wanting to push him into the mud. Hard.

The subplot between the doctor and his secretary is maybe a little unnecessary? But Kirsten Dunst is amazing so whatever.

I wish I had stayed.

• Rocky Horror Picture Show (1975)
• The Good, The Bad and the Ugly (1966)
• Star Wars: A New Hope (1977)
• The Third Man (1949)
• The Ladykillers (1955)
• The Big Lebowski (1998)
• Repo Man (1984)
• Stalker (1979)

Probably several others, but those are the first to come to mind.

I lost count:

The Marvel Cinematic Universe movies. I know it's popular to hate on them and point out flaws, but most of them are perfect "junk food" comfort food flicks. And some of them are really good!

I don't re-watch movies very often, and more than three times is rare as hens' teeth. Sometimes it's because it's an absolute classic, or sometimes it's because I'm weirdly fascinated by it. Let's see if I can remember those rare exceptions.

• Starship Troopers (good movie, and something about it charmed my socks off)
• Les Triplettes de Belleville (absolutely must-see, smashing masterpiece, no need to know French) (free to watch here!)
• Big Lebowski (words cannot describe)
• The Life of Brian (Monty Python's finest movie IMO, and a fascinating commentary on religion)
• Fire and Ice (good movie, and I found the rotoscoping utterly entrancing) (free to watch here and here!)

I’ve probably seen Hot Fuzz more times than any other movie. It was a comfort movie for a while.

Princess Bride

Pretty much any studio Ghibli movie. Have watched spirited away, Totoro, howls moving castle, valley of the wind, and many more more than 3x. Don't often rewatch stuff but have a soft spot for ghibli!

• Pulp fiction

• Napoleon Dynamite (will never not recommend this to anyone, regardless of cultural snobery)

Probably a bunch more

The Fifth Element comes to my mind immediately. It was my happy place.

The Lord of the Rings, It's what I watch when I felt lost.

Also, Nostalgia, another film I rewatch when I felt not belonging and nowhere to go back to.

Unusual or less known movies I've watched a quite a few times:

• Leaves of Grass

• A Scanner Darkly

• Red Lights

• Where the Buffalo Roam

• Fear and Loathing in Las Vegas

-2010: The Year We Make Contract

My mind is blanking on the others

Young Frankenstein

Airplane! with Zero Hour! (1957) immediately after
Fifth Element
The Death of Stalin

There are plenty (nearing my 60s, I've had plenty time to watch movies ;). So allow me to name just a few I always enjoy watching. They are in no order save the two first ones:

• '2001 A Space Odyssey'. There are movies, many are not that great, some are excellent and of those a few are true work of art, and then there is '2001'. I'm an admirer of most of Kubrick's work but this one is in a category of its own. I hated the first time I watched it, then I watched it again and was blown away, sequence after sequence. And I'm blown away every single time I re-watch it. It's one of the two movies I consider on par with the greatest books I've ever read.
• 'Les enfants du paradis' (Children of Paradise). Marcel Carné, 1945. A french movie and the second of the two movies I consider as good as the best books I've ever read. Maybe even more than 2001...
• '12 Angry Men'. Or what it means/should mean to live and to be a citizen in a democracy.
• Gone With the Wind.
• Ghost in the Shell (the original anime)
• The Dictator (Chaplin)
• 'The Life and Times of Judge Roy Bean'. I love this movie despite all its flaws. I love every bits of it, even its flaws. And I love its ending even more.
• 'Dances with Wolves'. I'm a sucker for Westerns and this one, right with 'Open Range' and maybe 'True Grit' (the Cohen version), which is also a great novel, is my all time most... loved Western. Not my favorite, but the one I love the most. Every time I watch it makes me wonder what the USA (and the rest of the world) could have been if they had managed to get rid of their hate (of the natives, and of nature). I should also list the Newman/Redford 'Butch Cassidy and the Sundance Kid'. But I feel bad for only listing so few as there are many more great Westerns and even a few truly amazing ones (there is also a lot of turds, I will admit it). This genre deserves a thread on its own as it so often overlooked or ignored because of its label. It's sad.
• 'Somewhere in Time'. next to Westerns, I'm a sucker for love stories. This one makes me cry every single time. I also like 'When Harry Met Sally', a lot.
• A History of Violence. I expected not much of it but it happened to be a great movie. With an amazing casting.
• The Birds (my favorite Hitchcock, so different from du Maurier's original short story which is also excellent, btw)
• North by Northwest (another Hitchcock, another of my favorites)
• Toy Story (the first 1, maybe the 2nd too), Ice Age (the 2 first ones)
• 'Singing in the Rain'. The movie I've watched the most, bar none?
• 'West Side Story'
• 'Scarface' (the one with Al Pacino).
• Kick Ass (the first one) made a huge impression on me. And gave me hope that all was not lost with contemporary US cinema that has grown afraid even of its own shadow and has started self-censoring, hard.
• A clockwork Orange.
• Full Metal Jacket (there is a lot I like less in it but it still is a great film)
• Barry Lyndon. God may have created light but Kubrick mastered it, in that movie.

There are so, so many more! Ozu is one of the directors I can endlessly watch and have a blast, I'm also a fan of Kurosawa. I have not even considered Italian (like, they were among the best) or the Russian cinema! Or even my own French movies: back in the days, French used to make a lot of great movies but that was before we too, like Hollywood, became so afraid of our own shadow that we started self-censoring... Sad times we're living in, bu that will pass.

Big Trouble in Little China

Princess Bride

The Adventures of Baron Munchausen

Tank Girl

Romancing the Stone

Fear and Loathing in Las Vegas

Where the Buffalo Roam

The Lord of the Rings - watched these many times now, and a couple of those have been back to back marathons. And yes, extended editions every time.

The Little Mermaid - The original Disney animated version. It’s possibly my favourite of what is known as the renaissance era.

The Muppet Christmas Carol - I watch this every year on Christmas Eve. I think I’m up to about 15 or more years now. It’s without a doubt the best version of A Christmas Carol ever.

Top three off the top of my head. I’m sure there’s more but the won’t match the number of times I’ve watched these.

The Rocky Horror Picture Show

Galaxy Quest

Hundreds of Beavers! It's an absolute delight showing it to someone who has never seen it before.

i don't even have an answer for that. but i grew up pre-internet and owned lots of video tapes.

i'm marveling at the notion that there may be people who haven't rewatched movies a lot?

• Star Wars trilogy
• Aliens
• Young Frankenstein
• A Christmas Story
• Die Hard
• Predator
• Terminator 2
• The Fifth Element
• Ghostbusters
• Spaceballs

Top secret, Back to the future, Star Wars (IV,V and VI), Godfather (all three), LOTR (all three), Goodfellas,

Just cause these haven't been called out by the top comments-

True Lies

The Hunt for Red October

How to Train Your Dragon

used to fall asleep to it every night

Most of mine have already been mentioned, but the biggie that hasn't is: the Back to the Future trilogy.

Not only are there lots of little details you probably don't catch on the first viewing, I'm surprised they don't make more millennial-and-older users' lists just from them being often the best thing on TV, in the ancient times before streaming.

I probably watched The Man from Earth (2007) over ten times.
