The name J.J. Abrams and the word “mystery box” have become rather synonymous given the filmmaker’s preference to keep any and all story details under lock and key until his film comes out, but that doesn’t mean he can’t have a little fun with the process.  Production has been underway on Star Wars: Episode VII for some time now, and as one can imagine, Abrams is doing everything in his power to keep the film’s secrets under wraps until next December.  That hasn’t stopped set photos and proposed story leaks, but Lucasfilm has taken a strict “no comment” policy on just about everything.  Producer Frank Marshall, whose wife Kathleen Kennedy is the president of Lucasfilm and producer of Star Wars 7, is currently visiting the film’s London set, and he recently shared an image on Twitter of a pretty funny propaganda poster that hangs on the walls of the soundstage.  It’s a humorous reminder to, simply put, keep your mouth shut.

Hit the jump to take a look at the Star Wars: Episode VII spoiler poster.  The mystery box opens on December 18, 2015.

If the poster looks familiar, that's because it's actually an existing poster created by artist Cliff Chiang as part of the Imperial Propaganda series.  Abrams and Co. deemed it a swell fit to adorn the film set, and it's hard to argue with their logic.
