This looks like the thread to ask. Does anyone remember the story about the Stardust Hotel during the making of Return of the Jedi and how Anthony Daniels was given the nickname of Stardust by a member of the crew on the first film? I can’t seem to find anything about it anymore with how searches are now overpopulated with Jyn and Rogue One. I’ve always seen that callback as a homage to that particular story. I believe also Anthony Daniels talks about it in the commentary of Return of the Jedi but it’s been awhile since I’ve listened to it while watching the film.
I found this that might interest you (second paragraph of page 52).
