This is in a more comedic vein, but I love the swordfight near the end of
Court Jester, where Danny Kaye's character is under the
Suggestion that he is the greatest swordsman in the world, but comes out of it every time he (or someone else) snaps his/their fingers! Hilarious! DK is quite an actor, and can make you believe that his character is an expert swordsman AND a bumbling Bard, switching from one roll to the other at the snap of a finger!
And who could forget the attack of the midgets, from the same movie?!?

Now THAT was a skirmish!
