It's a shame the destruction of Centauri Prime in B5 is so primitive as it has some points of similarity.
Not all Naboo cities need to look exactly like Theed, they just need the general feel (not all European cities looked the same during WWII).
There may be some of the awful League Of Extraordinary Gentlemen film which could be re-used too. Venice looks very much like something you might see on Naboo.
