IMO, best leadership speech in written English.
(Preference? Branagh or Olivier?)
Branagh. Olivier's delivery, the first time I heard it, struck me as artificial, especially the sliding rocket-note at the end, at "St. Crispin's Day-EEEEEEE!" Ouch!
That's even spotting Sir Laurence a Plantagenet point for his French last name.
I also liked the soundtrack of Henry V.
