There has been a lot of leaks from the Star Wars set that could at least annoy some of the film execs. Set pictures taken by spy drones and script leaks, and now, concept art.
These concept art look pretty legit (or they could be drawn by fans). You can see some Daisy Ridley (one of the actors) sketches, Adam Driver’s villainous role holding Darth Vader’s severed burned head, flying machines, troopers, Chewbacca and light sabers.
There are no comments from the official Star Wars yet.
