I know Bay thought that it would be a good idea to leak false information so that people won't know anything about this.
From what I gather, the only false information will be related to story and Transformers characters.
The false information WILL NOT be related to casting information. So if you see an article online that says "so and so is in negotiations to be in Transformers" such as Jonah Hill and Isabel Lucas, that stuff is real or it was just a rumor but was not part of their false rumor plan.
The reason why is because if you see what happened recently, Michael Bay had to confirm it himself that Jonah Hill and Isabel Lucas are not part of the production. The reason why? I suspect that the agents of both celebrities will have too much unwanted and or incorrect press about them and it would be responsible by Bay if in the event the information gets out of hand.
So considering he said that he was going to leak false information, he still has to keep the real information controlled so that it does not affect the parties that have nothing to do with the movie.
Another reason why I believe that this whole false information drama is going to bite the production back is because of things like the Aircraft Carrier deal. It was not officially announced that there was going to be an Aircraft Carrier Tranformer or Broadside in TF2 but recently Lorenzo Dibonaventura confirmed that it WILL NOT be in the movie.
If is one of those rumors that took a life of its own, and the producer is telling fans not to get hopes up, then they have already dissappointed the fans.
However if this is just another false information gag and there really IS an Aircraft Carrier, then people who know the game they're playing will already know.
So you tell me which would it be?
1) dissappoint the fans by telling them there is no aircraft carrier?
2) or telling them there is no aircraft carrier only to lead them to believe there really is one in the end (because the fans know there will be false info leaked)
If it is number 2, then they really did jump the gun with the false info strategy because now fans will just believe the opposite and they will know or at least have an idea of what will be in the film, thus already spoiling the movie.
So if its number 1, fans are dissappointed
And if its number 2, fans will already know who's in the movie because they'll believe the opposite.
I'm sorry to say this but the leaking of false information really won't work. It will get the hopes up of fans only to be dissappointed in the end or it will be spoil it for them because they will know to expect the complete opposite.
Its better to just have tighter security on the script and character designs. Thats just the way to go.
