J.J. Abrams is a very secretive filmmaker, and he's brought that trait to Star Wars: The Force Awakens. While Disney had no problem at all spoiling almost the entirety of Ant-Man and Avengers: Age of Ultron with countless trailers and TV spots, Star Wars: The Force Awakens has so far had only two teasers, a single trailer, and one TV spot for fans to pore over. Unfortunately for Abrams, the anticipation for this movie has meant that major story details, concept art, and behind the scenes photos have all been leaked over the past year or two, and not even Star Wars has managed to escape the dreaded paparazzi while shooting on location (whether it was in Dubai or England). Does it serve him right, though? Is the director's quest for secrecy actually damaging the movie's chances of success? Probably not in a significant way, but it's still an approach which has upset a lot of fans. After all, Abrams' "Mystery Box" already backfired on him once following the Khan debacle in Star Trek Into Darkness, so it really shouldn't come as a surprise that some have rejected his decision to keep so much of Star Wars: The Force Awakens a secret. As a result, even the movie's biggest secret - the appearance and fate of Luke Skywalker - has found its way online, and these are the eight biggest set leaks which are sure to have left Abrams fuming. Needless to say, there are potentially massive spoilers ahead...
