The Guns of Navarone, one of my Fav movies.

I was always impressed the way Anthony Quinn could walk into the role of a Greek commando or a Bedouin chief with such ease.

He told a story about the making of "Lawrence of Arabia". He studied T.E. Lawrence's book Seven Pillars of Wisdom about his character Auda Abu Dhai. He examined the photos and when he emerged from the tent on the location, fully made up and costumed, he said the Bedouins made such a fuss about the "return" of Abu Dhai, that David Lean came out of his tent to see what was up. He took one look at the man striding through the crowd with the excited Arabs around him and said, "Bring me THAT man..... and fire Anthony Quinn."

I cannot say if true or not but is was a great story.
