Character mistake: When Rommel leaves his French headquarters for Germany on June 5th for his wife's birthday on the next day, he erroneously states that date as 6th of July (pronounced yoo-lee), not June (pronounced yoo-nee). (00:29:30)
Character mistake: On the journey to meet Prince Feisal, Lawrence is offered food by his guide and accepts using his left hand. This would have been considered an insult as Arabs always eat using the right hand. The historical Lawrence would have known better. He had spent many years in the Middle East before the war.
