The last rumor we have heard about the Star Wars Episode 7: The Force Awakens trailer was that it will debut with the first outing of The Hobbit: The Battle of the Five Armies – but this rumor was shot down.
However, one worker from a cinema chain says that Disney will push the trailer next week, on the 28th, in exactly 100 cinematographs all over US. Not just that, but Disney also plans to have the 90 seconds teaser trailer in front of every movie, no matter what the studio releases those films. However, this is just a rumor, no matter how big and fat it may seem.
But, to support it, Making Star Wars has revealed a gif image, which seems to be taken from this teaser trailer.
