R2D2 is the only confirmed "Star Wars: Episode VII" cast member at the moment, but that hasn't stopped the production from getting underway. J.J. Abrams is reportedly using Abu Dhabi to recreate Tatooine, aka Luke Skywalker's home planet, and set photos from the United Arab Emirates capital have wound up on photo services (via The National). As ScreenCrush notes, the picture below is possibly the foot of an All Terrain Armored Transport (or AT-AT), which was made famous in "Star Wars: Episode V - Empire Strikes Back." Exciting! "Star Wars" is due in theaters on Dec. 18, 2015.
