Jake Gyllenhaal, Swedish-American Jew, and the Prince of Persia?

Observation of the week: virtually no one in the movie The Prince of Persia, is Persian. Furthermore, everyone in the film has a British accent.

Hmmmm, I may have to dust up on my history of Persia, but something tells me that this was, in fact, wrong. Grossly inaccurate? Pretty ridiculous, if not downright absurd?  Are North Americans that simple that applying a British accent to characters that are set virtually anywhere outside of our continent will suffice in making us "believe" in the authenticity of their foreignness?

I guess so....because goddamn that Swedish-American Jew, Jake Gyllenhaal, makes for one hell of a prince o' Persia. He pretty much had me at "Allo, gov'na", which is "Disney Persian" for "Salam"
