You are not looking at a real trailer for The Force Awakens. Sorry! It's phoney. Fake. And fan-made. But, you know what, for what it is, this is pretty good.
Uploaded by YouTuber Romeo Lux who wrote, "Awesome! Great tone to this trailer! Now I just can't wait for the real thing!"
As pointed out by YouTube commenters like Tobias Walker, you might recognise a line from the game The Force Unleashed ("I've finally drawn you out of hiding" was said by Rahm Kota) as an obvious giveaway that, of course, this isn't a real trailer.
There are other clues too, like Harrison Ford's quote "You guys got room in this battle for an old war horse." That, YouTube commenter Young Wyze points out, is from Anchorman 2. Then there's old footage as well as footage from other fan films.
Still, the whole thing is put together skillfully enough that the trailer has over a thousand likes on YouTube and that some people online are getting fooled.
