On April 16th, 2015 in Anaheim, California, the STAR WARS Celebration Convention will hold a one-hour panel (10 AM - 11 AM PT) dedicated to THE FORCE AWAKENS. It will feature writer-director-producer J.J. Abrams, producer Kathleen Kennedy and "special guests". Given that we know the next trailer for THE FORCE AWAKENS will be attached to AVENGERS: AGE OF ULTRON (which begins rolling out in theaters overseas on April 22), I think we can all search our feelings and conclude that April 16th will be the day said trailer a) debuts at Celebration, and b) officially hits the internet.
The trailer is probably already cut MPAA approval, so there are folks out there who've seen it. As is often the case, one of those folks got in touch with MakingStarWars.com, and gave a fairly detailed breakdown of what we'll see in the trailer. While I'm aware many of you want to read this, I, and many others, do not. So in lieu of posting the description here, I'm just going to point you to the relevant page and let you determine what you want to know. Feel free to say whatever in the talkbacks. Enjoy/avoid!
