Gandalf the grey/white
Merry
Boromir

oh yeah and and Sir Alec Guinness was obi-wan in the original trilogy and he is english

Hehe It's been a long time since I've seen those movies.

In the Chinese versions , I heard that Mandarin is spoken by the empire , and Cantonese is spoken by the rebels

I strongly doubt that, seeing Mandarin and Cantonese are practically two different languages (the same way, say, Spanish and German are different languages).

oh yeah and and Sir Alec Guinness was obi-wan in the original trilogy and he is english

I always saw it as the Rebels being the Allies and the Empire being the Nazis from WWII. Its just that the star wars Nazis spoke brit english instead of German.

Thats what Lucas was thinking when he wrote the films.  The Empire bears alot of resemblence to the Nazis - they are both racist, they both think one race is superior (aerians and humans), they both enslave a race they think is inferior (Jews and Wookiees) and force them to work in camps, the leaders of both rose to power 'legally' in democracies, and proceeded to completely take over the governments and rule as dictators, both of their elite shocktroops are called... STORMTROOPERS!  Hell the TIE pilots even fly like German pilots.  I wonder if the real stormtroopers had the accuracy problem.
