Total Film has put together a list of 10 Top Movie Put Downs. Mostly, I think the list isn't impressive. (#10--Schwarzenegger says, “Well that hit the spot!”when the villain explodes in his own soda ad. Kind of lame, if you ask me.) Most are just okay.
My favorite movie put down? It's got to be from Kill Bill, Vol. 2:
Elle Driver: That's right. I killed your master. And now I'm gonna kill you too, with your own sword, no less, which in the very immediate future, will become... my sword.
The Bride: Bitch, you don't have a future.
Hell yeah! Plus it precedes a pretty awesome fight scene. Definitely kick-ass.
