Representations of Arabs

The representations of Arabs are very different in the two stills that I observed. In the Indiana Jones' still, i realized that all the Arabs except for the big tough one are all wearing pretty much the same thing. They seem like they are all peasants in a small town trying to make a living. In the Lawrence of Arabia still, the Arabs look like they are all wealthy and powerful with jewels and bright colored clothes. I would think that the representations of both these groups of Arabs is pretty spot on. They wear the traditional clothes because most Arabs live in the desert and it suits them very well in the hot sun. I would say that Arabs are almost the same as Europeans in economics, science, and politics, they just do it a different way because they live in a totally different region where they can adapt to the environment. Hollywood over-glamorizes a lot of things, so maybe both the stills are totally nothing like what an Arab should look like. I've never been to an Arab country so I wouldn't know. All I know about Arabs comes either from movies or the news so I can't be sure what to think.
