Best swordplay ever??? Other contenders . . . . . .
Interestingly, my top two swordfights ever co-starred Basil Rathbone. In the first, he fights Tyrone Power (whose long family acting heritage included mastery of stage fencing) as Zorro. This scene in "jester" tops even that. Not only is the fencing crisp, prolonged and well-choreographed, it also incorporates comedic, panicked ineptitude. And you know the universal truth: Tragedy is easy, comedy is hard.
Another, longer classic is in "The Princess Bride" between Mandy Patinkin and Cary Elwes. They even witch hands (or did they flop the negative?"
Honorable Mention: Maureen O'Hara vs. Cornel Wilde (a member of the US Olympic team) in "At Swords Point." I never appreciated Errol Flyn, a bit of a hacker.
