Im surprised no has mentoined the Govenator. Those Conan movies were pretty good.
Nooooo, a swashbuckler has to fight with skill and speed, not strength, and also he has to be witty and to flirt (chastely) with the leading lady.

If he isn't using a rapier (cutlasses are acceptable for pirates) he isn't swashbuckling.

Tyrone Power is another good call, I used to love Zorro on saturday morning TV as a kid.
