Other mistake: It's settled that Lawrence takes 50 of Prince Faisal's men with him to fight the Turks in Akaba (as long as they get there through the burning desert). But to my calculations there's only 32 men riding with him, plus those young servant wannabe's who (without permission) follow the party.

1 other mistake - chronological order
Directed by: David Lean
Starring: Peter O'Toole, Anthony Quinn, Alec Guinness, Claude Rains, Jack Hawkins
Continuity mistake: The shadows in the scene with Lawrence sleeping on his camel are short because it's the middle of the day. In the next shot you see long shadows on the sand. When Ali wakes up Lawrence they are short again. (01:01:41)
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.
