Interesting to see that one of Richard Marquand clearly directing the Throne Room scene with Luke overpowering Vader (many claim GL directed the Throne Room scenes), but another with GL & Marquand sitting on the Throne Room steps discussing something. I think the late Richard Marquand has been unfairly dismissed over the years as being little more than GL's assistant director on ROTJ, I picture him more as the sort of director that was common in the Golden Age of Hollywood - handling the specific directorial duties on a film in service of the mogul's/producer's vision. A master craftsman, not necessarily an artist. Auteur theory (i.e. the director is the true 'author' of a film) simply isn't the all-encompassing truth so many believe it is, nor is it the best state of affairs. The likes of Kubrick, Scorsese and Lynch are the exceptions, not the rule. Even Roman Polanski has admitted that for him, Chinatown (my favourite film of all time) was really a job of work, as opposed to the somewhat warped and more personal films that are far more typical of his ouevre. The greatness and virtual perfection of that film was the result of a true collaboration between its writer (Robert Towne), producer (Robert Evans), director (Polanski) and lead actor (Jack Nicholson). From reading the earlier drafts and the various accounts of its making, had any one of those collaborators had too much control and input, Chinatown could have been a disaster that simply didn't work.
