We didn't get a new trailer for the upcoming "Star Wars" movie, "The Force Awakens," at Comic-Con this year, but we did get a look behind the scenes.

In a three-minute video released at Comic Con, Disney and Lucasfilm gave the world a look at behind-the-scenes footage from the new movie.

There are some other hidden gems in the video too. Let's break it down. But stop reading now if you're afraid of potential spoilers.
