For being "not a fan fan" of Star Wars- Tony Gilroy sure has no problem with putting in really subtle and fun details that appeal to Star Wars nerds while not taking more casual fans out of the moment. I'm not just talking about all the background Easter eggs (of which there are plenty), but his ability to re-create specific shots (the pan down a closing hatch to walking feet mimicking
Leia's Ep4 interrogating scene), answer subtle questions ("
how the heck do pilots get into TIE fighters when they dangle from the ceiling of the hangar bay?"),
helping turn a throwaway line into a subtle meme, and generally creating a setting that truly
feels like original trilogy Star Wars. That last part is the most important. Rogue One and Andor recreate details from the original trilogy faithfully (such as the interior of the TIE fighter cockpits), even
re-use old EpIV footage, and creating new locales and backgrounds in a fashion that they fit organically into the OT Star Wars universe.
Obviously, this isn't all coming out of Tony Gilroy's brain directly. But he's definitely got people he's working with that he's willing to listen to in order to get this stuff "right." He cares enough about the universe to make his creates feel like a natural extension of Star Wars. I would at least be interested to see how he could counter-weight his create force against someone like Filoni's.
