What bugs me is even CNN looks to TMZ as a source these days. TMZ isn't much better than the sleazy tabloids of the past, except you can't line a birdcage with them.
IIRC, there is mention in Once Upon a Galaxy of a gossip reporter conning their way onto the Empire set to interview Carrie, They were more interested in digging dirt on her mom than asking anything about the movie.
Once the movie gets underway, there were probably be paparazzi under every manhole cover, and people diving through Disney's dumpsters in the dead of night. Mr. Abrams will have his work cut out for him keeping the same veil of secrecy over the film he's managed to do with the Star Trek sequel.
