Wow, didn't know that, but it makes so much sense. I'm betting Hume did the Jabba the Hut stuff and the finale Darth / Luke battle (which has marvellous tracking shots).
For what it's worth, Mills actually photographed much of Return of the Jedi after Hume quit the picture.
Whereas Mills perhaps gave us Endor and the Ewocks looking like Star Wars the tv show.
NOT TRUE AT ALL!!!!!!!!!!!
Mills says in his autobiography that due to some person he chooses not to name, he himself got fired from the film.
Wow, looks like Bond isn't the only fandom beset by loads of misinformation.
