@Dom, we should bump your thread back up and discuss what you’ve done and more on what the original scene order might’ve been. I’m still wondering if Anakin was late for the briefing because he met with Padmé, does that mean the entire nightmare scene was reshoots?
I probably should bump my thread. At this point I’m one quick pass away from putting a pin in ROTS and finally releasing it for real (not just sharing workprint cuts).
As for the nightmare - no, that was definitely done during principal photography. The Making of ROTS book is decently comprehensive in terms of what was shot when (though I couldn’t locate the balcony scene when I was just skimming through it). One of the things though with the reshoots is in many cases it’s unclear if the scenes were written after shooting finished or were written before but just always scheduled to be shot after principal photography (because there’s definitely some of both).
I will say I may be wrong about the briefing, considering looking back in the book the general structure of that act of the film seems to have been in place since an early draft of the script - reunites with Padme > Grievous arrives on Utapau > nightmare > Palpatine appoints Anakin to the council (the briefing is not mentioned but still) - plus Obi-wan does say “you deserve your glorious day with the politicians,” so maybe the briefing is supposed to be the next day after all.
