When Rodolfo Graziani gives Omar Mukhtar his glasses back, he hands them to him with both hands. In between shots, the glasses are held upside down and then the other way around.
Omar Muktar takes off his robe with both hands to drape it over a fallen comrade, but after the cut he is suddenly holding a rifle in his right hand.
At the reception at the beginning of the film, an Italian officer complains about the abuses committed by the Italian army, saying they are not following the Geneva Conventions. The Geneva Conventions on the Laws of War were not made until 1949, 20 or so years after the events depicted in the film. The laws of war at the time would have been the Hague Regulations. In any case though, European countries as a rule did not accept that the laws of war applied to conflicts in colonial territories.
The closing epilogue reads: "Soon after the fall of Mussolini, General Graziani was tried and imprisoned. He died in 1955."
This isn't really true - Mussolini fell from power in 1943 and Graziani wasn't tried until 1948. Also, this implies that he was imprisoned for the rest of his life for his crimes in Libya - in fact, he only served four months, and that was for collaborating with Nazi Germany. Graziani was a free man for the last six years of his life and was never punished for his actions in Libya.
During the narrated introduction immediately following the opening credits, the Earth is depicted revolving backwards - west-to-east instead of east-to-west.
When Diodiece meets with Graziani and Prince Amadeo about starting peace talks, a map behind him, depicting the Horn of Africa, is inaccurate. The map clearly shows no borders between Ethiopia and the adjoining Italian colonies of Eritrea and Italian Somaliland, a situation that existed only after Ethiopia had been conquered by Italy and was united with the other two territories as the colony of Italian East Africa. However, this did not occur until 1936, and since the film takes place from 1929-1931, such a map could not possibly have existed at the time of the three men's meeting.
Mussolini spoke on an English-language map of Libya.
Mussolini is talking to Graziani in the opening when he looks the map of Libya, and says that all the green land is for Italy, but this is a topographical map that shows land greener as it becomes lower by sea level. Ninety percent of the area of Libya is desert.
