Is it tricky to write big gun-fights or not so much seeing as how thriller,mystery,war and western movies have been at it for decades?.Would reading up Nothing last forever (Die hard 1's source material) or Tom Clancy novels be a start at seeing how it's done?.Do things change b/c it's in the style of an Asian "heroic bloodshed" (like a John Woo) or Jet Li crime movie and I'm trying to put all those striking visuals into prose?.
