This is all nonsense. I’ve seen the old movies from the 1930’s and 1940’s, and a battle death is not very painful or bloody. All that happens is a person will clutch their chest and fall over. There is never any blood.
Well, gee, that's 'cause blood was invented by that Tarantino guy.
Once he figured it out, it splattered every where...even if they got shot in the foot.
I believe it was against the Hays Code to show blood spurting from a wound. The only ones I can remember seeing that did have blood flow was DOUBLE INDEMNITY and SHANE which shocked the audiences when the farmer (Elisha Cook Jr) was shot by Jack Palance.
