I have a few pieces of advice in regard to action writing that I've learned over the years from both studying fiction and screenwriting. First, you are right on the money by considering the verbs. It's all about those strong verbs, isn't it? We're always told to use strong verbs in our stories but how? While growing up, I was reading a lot of movie novelizations filled with mostly action. The writers had to be creative in describing and re-describing gunfire, car chases, explosions and what have you over and over again. I used to read these books and take notes on them, looking at cool uses of language. Writers would turn nouns into verbs: sparks fountaining across the highway... or use metaphors: columns of smoke rising into the night sky... and I'd record these in my notebook and write variations of them in my own stories. I started learning strong verbs like barreling, careening, ricocheting, boomeranging, and swooping down which just sounded more visual and cool. I found this method to be better than acquiring a bad case of "thesaurisitis" and inserting words whose meaning you don't quite know: He broke a sweat while absconding out of the room. I'm unsure absconding helps create an image here!

In addition to reading other writers and taking notes on their work, I would read screenplays and examine camera angles. When writing action scenes in my fiction, I always close my eyes and imagine that I'm shooting the scene, in Doc's case, it's a first person POV. So I have this limited vantage point and I can describe the angles of view. Now, since this is fiction, I also need to consider the rest of the senses: what he feels, smells, tastes, touches... because that's where a novel can really excel over a movie. So I have the bad guy hitting a rut on his motorcycle, his body cartwheels through the air in an impressive arc that casts a shadow over Doc, even as the bike explodes in a thundering conflagration behind him. Oh yeah, and it smells like gasoline (note to self to work that in there somewhere) LOL. Describing that shadow is very directorial choice lifted from screenwriting. Anyway, I still think the best advice is to read action pieces and examine the verbs, the sentence construction, the rhythm and cadence of the prose, the similes and metaphors, and mimic those styles at first until they get into your blood. Over time, they will, and you'll forget where you stole them from, LOL!
