See The Note J.J Abrams wrote to Star Wars Vii Stars. From Collider

As evidenced by last week’s debut set photo, principal photography is now underway on a brand new Star Wars film.  That’s an exciting prospect in and of itself, and while we really don’t know much about Star Wars: Episode VII other than the fact that the original trilogy cast is returning and it’s a sequel to Return of the Jedi (obviously), it’s neat to think that right now, at this very moment, a new Star Wars movie is being made.  To mark the beginning of production, director J.J. Abrams shared an encouraging note with his cast and crew, and the note has now made its way online.  If you’re looking for story clues or Easter Eggs, you’ll be sorely disappointed, but it’s nice to see how much Abrams cares about the many, many folks that are working hard to bring this film to fruition.

Hit the jump to check out the note and to read Abrams’ words of encouragement yourself.  The film stars Harrison Ford, Mark Hamill, Carrie Fisher, John Boyega, Daisy Ridley, Adam Driver, Oscar Isaac, Andy Serkis, Domhnall Gleeson, Max von Sydow, Anthony Daniels, Peter Mayhew, and Kenny Baker.  Star Wars: Episode VII arrives in theaters on December 18, 2015.
