It was a nice movie with laudable messages of courage, honour, love, peace, humanity, faith and very importantly, an attempt (not perfect, I agree) at unbiased portrayal of both Christian and Muslim sides. And Ghassan Moussad (portraying Salahuddin) has a laser-beam stare that will burn right through you

.
But too bad, many people who saw it were bickering over historical technicalities.
Now back to the arms and armour -- I like the part when Balian duelled with the Muslim cavalier for possession of the black horse. The sword (forgive me, but I do not know the name of it) used by the Muslim cavalier looked like a very efficient slasher with a mean chop.
Now, the close-up of Salahuddin's helm was a bit of a disappointment to my novice eyes. Having seen some of the more ornate helms put on auction before, I thought it could have been finer. But then again, functional armour may not be as ornate as parade fineries.
