Well, write the script, of course. Maybe, maybe not. Either way, you're not selling acting. No, what you're selling is your script and that's what you will be judged on. I'll pay anyone a hundred bucks who's managed to sit through that movie without feeling like he or she must've done something terribly wrong in a former life to be subjected to this kind of torture.
Action is good.
Action is important, but you don't have to spend a lot of time at Blockbusters to realize that action doesn't make good movies, even if it does rake in the green. Because without structure you have a story that comes across like telling someone about a dream you had the night before. Because structure is the very reason why stories are important to us. Because without structure a story ends up just as messy as our every day lives, which is not what we go to the movies to see. At its simplest, structure can bee seen to fall into the three acts movie execs are so fond of, but this is misleading.
