I know that the standard #1 JCVD movie is Bloodsport. That is up there for sure. For me though, I have to say Lionheart takes the cake. In my mind, most underrated action movie of all time. Fight scenes are "ok to pretty good", but it actually has a very original story line to it.
Full disclosure...I have not seen:
**Hard Target (I hear this is up there)
**JCVD
**The Quest
