This week Star Wars director J.J. Abrams and Producer Kathleen Kennedy sat onstage at Star Wars Celebration 2015 - and BB-8 rolled up. Sitting beside a couple of the R2-D2 creators - originally fans, hired by Lucasfilm and Disney for the next movies - out rolled R2-D2, then rolled out BB-8. This spherical droid we first assumed was a special effect. Now we know he's real. He rolled out and moved around - he's a real-deal piece of equipment - remote-controlled, of course, but real metal hardware.
