Yes, we've all already seen this trailer for Star Wars: The Force Awakens at least 60 times. There is no new footage. It is not an addition to the meager clips we receive as we all await the release date. But it HAS been redubbed with acapella, which is kind of cool. Music, sound effects, and even dialogue has all been recreated by this college student, and it's, at the very least, an additional something to tide you over until the movie's actual theatrical appearance.
And it gives you a great idea of what The Force Awakens might be like if it were directed by Elizabeth Banks. No complaints here.
