How to Construct a Fight Scene

It's rare that a fight scene will justify itself as more than just a display of people punching or shooting at each other, because the outcome is rarely ever actually in question. So if you are going to do some kind of action scene, I find it really useful to show me something that I've never seen before. This is why like a Jackie Chan or a Tony Jaw fight scene is so much more compelling than a lot of the other ones. Or B, just make sure that there's some actual uncertainty that maybe the characters involved might actually die even though they're on the poster.
