Thanks
The film originally did open with the flashback, it sets up Leia being a jedi as well as subtly emphasising that Luke and Leia are in a way the heart of the film(which was the directors intention) , the planet they trained on is the one Rey is training on, Luke’s search for the wayfinder in the jedi books is the starting point for the crew’s journey, Leia’s involvement in her sons awakening to the light, their lightsabers in the battle against palps and last but not least their ghosts handing Rey the mantle of Skywalker.

That Vader/Kylo fan film could come in to use if needed, maybe a quick flash as Kylo meditates on the helmet, we’ll see.The cantina shots in the Mandalorian will be handy to use also.

These are just concepts and ideas that I’ll be throwing around, if anyone wants to use them, feel free do so.
