I watched the movie several times because I was fascinated with the historical accuracy of the clothing, cultural enactments and archery equipment and shooting styles depicted in the movie. People nowadays do twist their knuckles into the string when using a thumbring usually to tighten a loosely nocked arrow to the string and press it against the bow for stability before release. But the movie used this movement to preface a somewhat mystical achievement of this main character , the disenfranchised son of a fallen nobleman. This character’s only salvation was his dedication to his archery using his father’s Korean horn bow.???
