I've been researching interview material for the MAKING OF RETURN OF THE JEDI STAR WARS AFICIONADO magazine coming out at the end of the year. So far in my interview perusals, only Carrie has talked about George Lucas giving different direction from Marquand on one days filming of the Jabba Palace set. There are rumours that Alan Hume, Marquand's long time cinematographer, left filming at ELSTREE because he was annoyed at the way Marquand was being treated-there are pics of Hume's assumed replacement, Alec Mills, filming scenes with Marquand in March 1982 during the Emperors throne room scenes but, as far as I'm aware, Hume was part of the filming team that went to Yuma and the Rdwoods from April, working alongside an additional American cinematographer (due to US filming rules).

Marquand DID direct that film, and Lucas was HEAVILY involved with him on it, especially on the effects side which Marquand was not used to. Marquand did his first cut of the film with longtime film editing colleague Sean Barton. Then Lucas worked with him-Lucas insisted that they worked together on the editing- on a refined version which became the film we know now, working with Duwayne Dunham with extra help/trusted editing advice from Marcia Lucas Text
