The full note reads: "Dearest Cast and Crew, What an honour it is to work beside all of you, on Star Wars Ep VII.

"I can't thank you enough, for all work past and future. Let's take good care of not just ourselves, but of each other.

"Amazing, but true: the world awaits this film. Let's give 'em something GREAT. xo JJ"

Set to open next December, the film will star franchise veterans Harrison Ford, Mark Hamill and Carrie Fisher - along with newcomers John Boyega, Daisy Ridley, Andy Serkis, Oscar Isaac, Domhnall Gleeson and Max von Sydow.
