For me, the distinction between documentaries and feature films is not so clear - my "documentaries" were largely scripted, rehearsed, and repeated, and have a lot of fantasy and concoction in them.
It's all movies for me. And besides, when you say documentaries, in my case, in most of these cases, means "feature film" in disguise.
You should bear in mind that almost all my documentaries are feature films in disguise.
