There's some casting confusion when it comes to who played what in Return of the Jedi; Alan Harris, Bossk's original actor was on the set of Return of the Jedi, so it would be assumed that he played Bossk, but that isn't necessarily true. According to a recent interview with Trevor Butterfield (an actor who played multiple parts in the movie), he wore the Bossk costume during some scenes because Harris was doubling for Jeremy Bulloch as Boba Fett. Does anyone have any clarification as to which scenes Harris and Butterfiend played Bossk? When asked about ROTJ, Harris still says he was Bossk during at least one scene, so I think it's possible that he was played by two actors. In a related note, what scene was it that Harris played Boba? Personally, it sounds like Trevor Butterfield played Bossk during the palace scenes, while Harris played Boba during the Lapti Nek sequence. Alan Harris could have also played Bossk during the Sail Barge scenes.
