From StarWars.com: The first behind-the-scenes photo from Star Wars: Episode VII hit Twitter last Thursday, featuring director J.J. Abrams, Lucasfilm president Kathleen Kennedy, and a certain blue and white astromech droid — who StarWars.com can now confirm will indeed be in the film.
The other two guys pictured are Lee Towersey and Oliver Steeples, Star Wars fans and members of the worldwide R2-D2 Builders Club.
Glad to see the return of a classic character to the big screen for the next installment of Star Wars.
