Star Wars: Episode VII - The Force Awakens (2015)
Its been known for quite some time that a significant portion of The Force Awakens takes place on a desert planet (its right there in the first teaser from last November). Many fans assumed that said desert planet was Tatooine, which is part of five of the six existing movies. However, Abrams insists that it's not Tatooine, and is instead a new planet called Jakku (at least, that seems to be the accepted spelling on the Internet).
