In no particular order, I'd probably pick Terminator 2, Die Hard, Robocop, The Dark Knight, Heat, Kill Bill 1+2, District 9, The Crow (been awhile since I've seen it though), Speed, and maybe John Wick.
There's probably quite a few I've missed out on, especially foreign action films.
What are your picks, either popular or obscure?
Mad Max Fury Road. Just never stops
Ong Bak is a stand out martial arts movie
13 Assassins. It's directed by Takashi Miike to give you an idea of what you're in for.
Terminator 2
Aliens if you want to count it as an action movie.
Die Hard.
Hot Fuzz
Django Unchained
The Raid. The movie that introduced "The Hallway Scene"
Hero
Crouching Tiger Hidden Dragon
Dredd
Most of the Fast and Furious movies
Layer Cake
Red Cliff
Underworld
Baahubali
Dog Soldiers
I came in here to find The Raid because it's so goddamn good, probably my favourite action movie, but as Hallway Scenes go, isn't Oldboy earlier?
