To get a good story and character across you have to pick just the right person. I was thinking on doing my documentary about soldiers in Afghanistan. The have plenty of stories and opinions which makes for an interesting watch. I know a soldier in the Army who is currently in Afghan. The documentary will highlight daily life and how much of a struggle things like temperature and hygiene are. It will also highlight the fun parts of being over there and the perks such as respect from everyone over here.
