You should really read the St. Crispan's Day speech from Shakespeare's Henry V. It will give you an understanding of the power of this man. I hope this film is historically accurate. Also, maybe just do a google before you film next time?
I agree with the above, re the speech. However the amount of times I've had to correct. 'Mericans for saying this is based on the Shakespeare play has annoyed the shit out of me. This movie is clearly based on the historical story. Shakespeare only wrote about it 150 years later. As it was a great story and part of history in my country the UK.
