Det var först tänkt att BB-8 skulle haka på Rey till den där avlägsna planeten för att försöka hitta Luke. Men så bad Rian Johnson om hjälp från JJ Abrams om att byta ut robotarna och helt enkelt låta R2-D2 följa med istället, detta rapporterar Entertainment Weekly som Episode IX-regissören Rian Johnson.
"Yes... The big favor was, I asked if R2 could come with Rey, and if BB-8 could stay behind with the Resistance. Originally it was BB-8 who went with Rey, which makes sense for the story in a way. But I asked, 'Can you do me this solid and switch the droids?"
Han fortsätter sedan med att berätta vilken den tuffaste nöten var att knäcka gällande filmens manus:
"Figuring out where his head was at was the very first thing I had to do when writing the movie. I had to crack this. And it had to be something for me that first and foremost made sense. Why did Luke Skywalker go off to this island?. That was the starting point, and that's what the entire movie explores." Länk
