If
you think that those special things that Xena does are uniquely
Xena, you're wrong.
But, of course, Xena does these things in her own unique way...
In Drunken Master 2, Jackie Chan drinks industrial alcohol & spits fire, is set on fire, is hit by large barrels...you get the picture...
But in the meantime, Xena spits a pretty mean fireball herself...
as does this guy...
When Xena does the neck thing and gives her "I've just cut off the flow of blood to your brain..." speech it makes me think that she must have learned it from Asia the Invincible, the Brigitte Lin character from the SWORDSMAN 2 and SWORDSMAN 3: THE EAST IS RED. There are pressure point scenes galore in both these movies, as well as many other HK movies.
