so it's about jihad
Sure this must have been mentioned before, but I was just rewatching after seeing it years ago and it seemed quite obvious that the story parallels many realities of our own world. The spice which is the most important commodity obviously corresponds to oil whilst the desert planet Arrakis parallels the Middle East, control of which has been handed to various royal houses by the vested commercial and political interests of the evil empire (the West)... wow just had a little earthquake as i'm writing this anyway... also the name Muad'Dib I'm pretty sure sounds a lot like an Arabic name.
It's quite interesting because the story obviously sympathises with the people of the region, whereas now it would be difficult to find a western audience sympathetic to jihad for obvious reasons. yet the underlying reasons of oppression portrayed in the film remain unchanged. so I guess this film actually glorifies,or at least justifies, jihad. Wow, I didn't get that first time around but then again I was only 12 and 9/11 was a decade away.
