In that play, Shakespeare invented the war movie. Henry inspiring his “band of brothers” to battle against overwhelming odds, combined with scheming politicians, officers from different parts of the country, grunting doughboys, and scurrilous commoners, all brought into wider focus by the narration. There’s a love interest too.
There was the Iliad.
Shakespeare is good but he was not Orson Welles nor would he have wanted to be. War Play, yes, War Movie in 1599, NO! I remember a movie where they showed a MINIMALIST production of Henry V, very cut-down, bare stage and about ~7 performers. What I saw was still recognizable, still good but lived up to the "Chorus' Introduction" that calls upon the audience to use their imaginations! Amazing!
