Rogue One

Cabin in the Woods. Doesnt even matter who your favorite character is!

James from 12 Monkeys.

Donnie Darko and Hero are the only two movies I really like that I can think of where the main character dies at the end.

Gladiator

Terminator 2

Rocky Horror Picture Show

Star Trek II, Spock dies at the end. Oh oops they resurrect him in Star Trek III. Hmm.

How about Thelma and Louise? IDK if there is a sequel.

Dr. Strangelove, the Slim Pickens scene at the end? No idea whether he got brought back either.

The Prestige

I love this movie. It's one of the few I'll gladly rewatch because it keeps me engaged and the story keeps unfolding until the very end. Plus it has David Bowie playing Tesla which is one of my favorite people from history. If you haven't seen it, watch it!

The original The Wicker Man is almost perfect in this regard.

Not the main characters but:

• Lucky Number Slevin (IIRC)
• Don't look up

Fallen

Several films on my list have already been mentioned, so here's two that have been overlooked:

• Falling Down
• Gran Torino

Doctor Horrible Sing-along-blog

Man On Fire

Braveheart

Ikiru.

Excalibur (1981)

Arthur is impaled, pulls himself down the length of the spear that has impaled him, and uses Excalibur to impale his godforsaken son.

The greatest Arthurian movie ever made, bar none.

Green mile?

Butch Cassidy and the Sunset Kid

The Fountain

Pan's Labyrinth

Absolutely fantastic, I consider it a masterpiece. Definitely one of my favorite movies.

30 Days of Night is the first one that comes to my mind.

Aniara. If you haven't seen it, it's so worth a watch.

Bladerunner 2049, can't believe that hasn't been mentioned yet.

Sunshine.

18 hours and nobody has said Avengers Endgame?

Also, to be topical since it's early November: V for Vendetta

Harold and Maude.

Not a movie but The Sopranos is a good one.

Great film! The transformation scared the crap outta me when I somehow saw it on tv as a kid.

Children of Men was also a good one. Trying to think what others, but I love when the hero dies because life is rarely fair and just and an unlikely happy ending ruins a story pretty effectively.

Train to Busan

Idk if "In Bruge" counts since you technically dont know if he lives or dies.

Cool Hand Luke

Needless to say, every answer on this list spoils the movie. But, really, how it happens is as essential as what happens.

Everyone

• Melancholia (one of the saddest movies I've seen)

• Knowing (a little Nicholas Cage never hurt anybody)

• Don't Look Up (so well done, great soundtrack)

• On the Beach (1959, classic!)

• Sunshine (Alex Garland's swing)

Religious undertones

• Constantine ("coffin nail")

• Dogma (God/Alanis Morissette is the real hero)

• Meet Joe Black (the first death is the hardest)

Anti-Heroes

• Logan (heroes never die, right?)

• White Heat (1949, classic!)

• Kiss Me, Deadly (film noir, "the great whatsit")

• Dancer in the Dark (Björk, another saddest film)

Lawrence of Arabia.

Sinners. What a great time; I was sure everyone was gonna die before I knew the theme of the movie.

Iron Giant

... okay well sorta

Se7en

Two things that come to mind are ones where it seemed that way. In the movie enemy mine about or maybe over an hour into it it seems like the protaganist dies and it was going to end on one heck of a gloomy note. Especially seeing it in theaters before cell phones when you did not know the exact time. Then also in the supernatural series at one point which I think was the season 1 finale it looks like everyone died. I was super hyped because I was thinking the show would follow a different group of hunters every season that bought it fighting the supernatural. Don't get me wrong the series was still good but it could have been so epic.

The Poseidon Adventure.

Both films investigate human-bonds, and self-sacrifice for strong-held beliefs. High recommends.
