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.
Lawrence of Arabia (1962)
1 character mistake
Directed by: David Lean
Starring: Peter O'Toole, Anthony Quinn, Alec Guinness, Claude Rains, Jack Hawkins
Factual error: When Lawrence arrives at the Suez Canal, the ship which sails past is The Priam, of a 1950's design, and I think actually belonged to a company called "Blue Funnel Line."
General Allenby: You acted without orders, you know.
T.E. Lawrence: Shouldn't officers use their initiative at all times?
General Allenby: Not really. It's awfully dangerous.
