Action films, like the one I'm creating right now, involve extensive choreography, as demonstrated here in this picture of a fight scene in the Dark Knight rises. There are a number of good classes in Chicago for action choreography. Even if you don't live in Chicago, you're likely to find one nearby. If not, go to a martial arts class; you'll learn something.

I've also found that listening to certain film soundtracks can really get you in the right mindset to come up with plot lines, screenwrite, edit, or think about your film. If you download Spotify, you can listen to basically any music for free, and the only cost is a short add after every six/eight songs or so. I listened to the Dark Knight soundtrack while writing my current action film.
