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?
Oh shit, I forgot about Carpenter when I typed up my list. Escape from New York was also pretty decent for its time imo.
It's a solid action movie for sure, Carpenter put out some great work in his time.
