Giamatti miscast?
I like Giamatti (he was great as John Adams), but playing a British sovereign?
Although it is true the language back then was not yet "the King's English" (although John was the first to speak English), there were several times when Giamatti used American hard "r's" and his loud, barking manner did not befit a cultured and educated monarch, even if he was hated and treacherous. I just could not picture him as John; in the first scene, I thought he was simply the King's ambassador.
