JJ Abrams has been heavily backing the UNICEF fundraiser that is currently in progress on Omaze.com. Not only has he promised that one of the donors will have the opportunity to visit the set and appear in a scene of Episode VII (most probably as an extra), but also in the video below he now adds the fact that the winner will also receive an advance screening of the film for themself and twenty friends in a theater in their hometown. As you can see in the video he makes this announcement standing in front of an X-Wing fighter from the new film.
