That will inevitably lead to plenty of speculation about how that fits into the plot, although the most logical inference is that this means the movie more heavily leans on Luke Skywalker. However as technically Luke was never a full Jedi, there’s always a chance another Jedi Knight has survived somewhere who we’ll be introduced in the sequel (and of course that also leaves room for a few force ghosts too). Some have also speculated that it does refer to Luke, but that the fact he’s the ‘last’ means that Rey’s future is in something different that the old order of Jedi and Sith.
Daisy Ridley, Carrie Fisher, Adam Driver, John Boyega, Oscar Isaac, Lupita Nyong’o, Domhnall Gleeson, Anthony Daniels, Gwendoline Christie and Andy Serkis star, with a December release date set. Hopefully it won’t be too long until we get a trailer!
