OK, spoilers ahead for Return of the Jedi, so turn away now if you dont want a small part of a film made 30 years ago revealed. Still here? Good. The fact that Yoda physically dies in Jedi, means that a spin-off film is going to have look at two points in his life. Either "Dagobah Days" from the end of Episode 3, where we watch him explore a swamp and build a bungalow. That sounds unlikely, so its probably going to be his early days as a Jedi. Ive already laid out my problems with that, and the air of mystery that is essential to the character being diminished, but Ill also always have in the back of my mind that I know how his story ultimately turns out. I also know he wont die in the prequel, removing any sense of danger from proceedings.
