I know next to nothing about Archery and hunting with a bow. What I find interesting about that video is the lost history of how Archers used to operate. Holding and shooting multiple arrows in rapid fire succession seems completely logical once you see it. Since I don't know anything about archery, I always took "Hollywood's" version of ancient archery as the way it actually was.

One interesting tid bit is when movies say "Fire!". The term "fire" wasn't in the lexicon back in those days and didn't appear until guns were invented. More than likely, they said "loose" or something like that.
