Since the moment he was first revealed, BB-8 has emerged as a real fan-favourite from Star Wars: The Force Awakens and a toy which has sold out months before Christmas (good luck with that, parents). Like R2-D2, the noises made by BB-8 do give off an idea of his or her emotions, but it turns out that the movie found an even better way to achieve that; they gave BB-8 facial expressions! "You could move one component and the face would start to have a slight sad look about it or slightly aggressive," explains Scanlan. You want them to be able to talk to you before they move. And if they can do that, then the movement adds extra on top. Whether or not BB-8 lives up to the hype remains to be see, but as of right now, it's not remotely hard to imagine this unique little droid becoming another beloved Star Wars icon.
