“If you watch ESB and ROTJ back-to-back its actually quite jarring to hear the US accent from an Imperial officer right at the start of the film - in ESB the British accent was the voice of the Empire’s officer class and it gave the Empire a certain haughty aristocracy that worked very well.”
As an Australian, I barely notice the contrast between the American and British accents, they just all sound equally foreign to me compared to the Aussie accents I hear everyday so I have personally never considered this a continuity error! 😊
