Post-Colonialism and the Arabians

“Arabia” has always been a hot topic. It plays a key role in the geopolitics of the Middle East, as it's oil reserves are abundant. These two stills from Lawrence of Arabia and Raiders of the Lost Ark show two representations of Arabians. Raider of the Lost Arc is part of the Indiana Jones series starring Harrison Ford, releases in 1981. On the other hand, Lawrence of Arabia is a stand-alone epic released in 1962. Looking at these two stills proves to be very interesting right off the bat in that my assumption of which movie was released first was completely wrong. The still chosen from Raider of the Lost Ark is of Indiana Jones facing off with an Arabian dressed in a head-to-toe black garment. I would assume that this representation was that of an earlier time, making the Arabians about to be barbarians. The still chosen from Lawrence of Arabia presents the Arabians as being much more civilized, sitting at the table and in the same dress as the white man, Lawrence.
How do these stills relate to colonialism and post-colonialism? Well, I would say that the still from Lawrence in Arabia shows a civil, colonized Arabia whereas the still from Raiders of the Lost Ark depict an Arabia in which the people are running wild due to lack of Western rule. They are struggling to find their independence and in doing so, they have gone back to their primitive ways (or at least this is what Hollywood would have us believe.
