blocks, making the action confusing and hard to follow. On this film, the final battle in Egypt was devised to make it easier to follow the action. Four days were then spent in Jordan; the Royal Jordanian Air Force aided in filming at Petra, Wadi Rum and Salt because King Abdullah II is a big fan of science fiction movies. Filming continued at the Place de la Concorde in Paris with second unit shots of the Eiffel Tower and the Arc de Triomphe.
