I was imagining the other day that most war films and scenes are filmed with people faking shooting. Sometimes wars scenes are not even using blank rounds, like in Star Wars. This leads me to wonder if anyone has ever filmed a major movie without using blank rounds, in order to provide some bizarre level of realism. One wouldn't have to worry about acting or special effects to make it appear real, but it would probably be too dangerous and illegal for most. Still Film has a long and crazy history and the human race has seen many movies.
Of course, many documentaries have footage of live warfare, and possibly some avant-garde video art exhibits have done so, but I mean just what we might consider a regular movie with at least a TV, VHS, or Theater release.
