I think a highly stylized, fully choreographed sword fight would knock them all dead...unfortunately, it would need to be in the Hollywood style of screen fighting to be remotely entertaining to the unwashed masses, or MOPs as they call it over on the other side of the pond. You could always add elements of real swordplay, grappling, the odd punch or kick even.

Watch the man in black...he's actually grinning at one point, like he's just having himself a blast! And the guy in red, I want a hauberk fitted like is!
