The problem isn’t what Gilroy is doing, it’s that Disney is moving production forward, not pausing it until he comes back.
Sorry maybe I’m just missing something or don’t understand enough about the situation, but where is it being reported that production is moving forward? If Gilroy cannot function as a producer without also performing writing duties, why would this restriction not apply to any potential replacement? Isn’t Lucasfilm (or Disney) required to be a “Guild Signatory” in order to hire WGA members? If so, wouldn’t that mean that if they replaced Gilroy with a different producer, that producer (1) could not be a WGA member and therefore could not write, and (2) would only be able to perform producing duties. Therefore, either (A) the scripts are completed and production can only proceed without modifying the scripts or (B) the scripts are not completed and therefore it would be impossible to move forward with production (or at least the parts of production that weren’t written yet).
Again, I don’t know too much about all this so maybe I’m missing something here. Is the fear that Disney will just replace Gilroy and then just ignore Guild Signatory obligations by lying about any additional writing work performed?
