The hallway fight scene in Old Boy
Pirate AND writer!
The Bagghar chase from The Adventures of Tintin.
Looking for some stories?
The Mask of Zorro had some of the best cinematic sword fights ever filmed, and all within the confines of (more or less) realistic situations note . When accounting for more fantastical sword duels, Anakin vs. Obi-Wan in Revenge of the Sith is right up there. Sometimes CGI makes people believe nothing was really there, but the swordplay between the two of them was genuine.
Superman vs. Zod in Man of Steel is also one of the greatest superhero bashes ever put in live action. The fight between Superman and Zod, Ursa and Non in Superman II is still impressive today, considering they had to do things with more practical effects.
The overhead train chase in The French Connection.
You can't even write racist abuse in excrement on somebody's car without the politically correct brigade jumping down your throat!
The Raid 2 - the prison yard riot and car chase sequence.
HIGH IMPACT SEXUAL VIOLENCE
Seconding the hallway fight from Old Boy. Also, the last stand from The Wild Bunch
ALL CREATURE WILL DIE AND ALL THE THINGS WILL BE BROKEN. THAT'S THE LAW OF SAMURAI.
From the guys that brought you You, Me, and Dupree.
Honorable mention
. I know it technically isn't "film", but whatever.

Didn't we already do this thread? No, wait, that was gunfights.
Anywho, here's Jackie Chan with his weapon of choice:
Keep Hope Alive
Seconding Superman vs Zod and the Smallville fight.
This is one of the best action scenes ever put to film
Also the river battle from Desolation of Smaug for pure entertainment factor.
Stand Fast, Stand Strong, Stand Together
Face me now, Bitch!
The final fight with the mutos in sanfrancisco in Film/Godzilla2014 is a great monster brawl. With gypsy danger vs. oatchi being second and Godzilla vs. destoroyah is third.

Here's something from the 80's, a classic era for action:
I can't believe that the greatest action sequence of all time involving guns hasn't been mentioned!

You're right. Thus I now feel obligated to show it here.

Oh yeah, the hallway fight from Old Boy WAS amazing. 
The action scene to beat all action scenes.

I don't know how much the Toei Summer Movies qualify, as some of them are barely feature-length, but this is one of the highlights of Paradise Lost
The beach assault scene in Battle Royale II: Requiem. Can't find a clip that just shows that, I'm afraid.
The Convoy attack from Clear And Present Danger.
The triplet twin fight scene and the final fight of Man of Tai Chi.
"All you Fascists bound to lose."
I liked the final assault on the Russian/Koreans base in No retreat no surrender 2. That shit was crazy. Hell any of the action scenes in that movie were good.....memories.
But storming the beaches of normandy in saving private ryan gave me the chills. Grab some headphones, crank up the volume and tell me you don't get goose bumps.
What would you say is/are the greatest action scenes in cinema? There should be metric tons of candidates to choose from.
If you ask me, I'd say the Omaha Beach scene from Saving Private Ryan, with the climactic battle from The Avengers being close second.
