Corrected entry: During this time period the "Turkish" flag that was shown throughout the film was not the flag of the Ottoman Empire. Rather it is the modern flag of the Turkish Republic, which was founded in 1923.
Corrected entry: In the scene where Gassim is trudging through the Nefud Desert after having been left behind by Lawrence's party heading for Aqaba, the sun is rising. The party is traveling north towards Aqaba through the Nefud, yet the sun is rising on Gassim's left, which would be the west. Be aware of the sun's position during the following scene where Lawrence returns to the Arab camp in triumph after having rescued Gassim. The director used shots made at various times of the day, as can be seen by the characters' shadows.
Corrected entry: Peter O'Toole is left-handed and he plays T. E. Lawrence, who was right-handed, so he had to pretend to be right-handed. But pay attention to the scene where he talks to Anthony Quinn, soon after the arrival in Akaba: Peter pretends to write on a paper using his right hand, but he moves it from right to left, instead of left to right, as Arabic is written.
