Disney’s huge D23 convention has just fired one of its big guns, as they revealed a new behind-the-scenes video for writer/director Rian Johnson‘s Star Wars: The Last Jedi.

There’s a lot of interesting material here, including the first footage of new characters played by by Laura Dern and Benicio Del Toro, as well as a glimpse of Carrie Fisher in her final role as Princess Leia.

This episode of the long-running franchise will obviously be an emotional journey. Star Wars: The Last Jedi is released on December 15, 2017.
