I'm not saying it's true, but there is a rumor that the movie may be delayed. The change of date in Brazil (from July to September) was something strange because everyone knew about Olympics. There is no reason to move to September. July is the school holiday period in Brazil. I do not know if there was a change on other dates. I heard a rumor that Lin would be dissatisfied with the production of sound. Would it be reason to delay? Others have said that Paramount did not like the movie. I think that only after the 20th is that we will know what will happen. Conspiracy theory?
Seems odd they would go and set up a fan event if they didn't like the film. I guess it's possible it could be delayed due to technical issues, but Paramount has already booked a ton of theaters for July 22nd and it seems awfully late in the game to change it now.
