Factual error: The U.S. Paratrooper uses his "clicker", and the German answers with a "double" click-click - click-click. The Paratrooper stands up, and the German soldier shoots twice with his Mauser K98 without pulling back the bolt between shots, which is impossible.

Suggested correction: There could have been another German soldier present who fired as well.
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)
