From the man, the myth, the legend jovan_scorn: Entertainment Weekly's list of the Top 100 Action Movies of all time. Bolding the ones I've seen, and you can do the same if you wanna play along. Too lazy to count them all up but I'm batting nearly .500, and if this was baseball numbers like that would get you into the Hall of Fame.

EW ranked the Top 25 by number, in case you're curious. Though the list is kind of suspect - Titanic isn't exactly what I'd call an "action movie", at least not in the same vein as Rambo, Terminator, or Robocop. But it's still a fun way to kill some time on a Sunday afternoon.
[EDIT]: Finally counted them all up after all. Very nearly hit 75%...apparently I'm a big fan of senseless violence. Who knew?
