We've seen some glimpses of the movie in a teaser trailer, but we get a pretty concentrated dose in this behind-the-scenes vid that shows off some cool fight scenes (Rey with a light saber!) and a bunch of weird new creatures (WTF is that glassy-looking fox?). Also, it's always fun to hear John Boyega, who plays ex-Stormtrooper Finn, using his real-life British accent. We also see some great footage of Carrie Fisher (hard not to get a little choked up there).
One of the themes of this video seems to be that Johnson's script is going to be a little shocking. Given that there's a chase scene in Looper that haunts my dreams to this day, I can absolutely believe that there will be a few unhinged moments in The Last Jedi.
