Though Disney won’t be hyping Star Wars: Episode VII at Comic-Con, director J.J. Abrams has released a video from the set of the movie during which he gives fans a first look at an X-Wing fighter from the new film.  In the video Abrams promotes an excellent cause, the "Star Wars for Change" campaign to raise money for UNICEF’s Innovation Labs, which are attempting to create new ways to help the world’s disadvantaged populations.  As he talks the camera pulls back to reveal the full X-Wing fighter.  A flight suit-wearing pilot climbs in the plane and a mouse droid scurries across the ground underneath the plane’s fuselage.
 
A photo released in June appeared to confirm the presence of the Millennium Falcon in Episode VII, with the iconic fighter apparently under construction in the background (see "New 'Star Wars' Set Photo"), but this is the first look at the complete prototype.

The eagerly-awaited Star Wars: Episode VII is slated to debut on December 18th, 2015.
