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?
The Good, the Bad and the Weird. It's a reimagining of the Good, the Bad and the Ugly set in 1930s Manchuria and has an equally awesome soundtrack
