Star Wars Episode VII Principle Photography Started

Via Bad Robot's Twitter page, we have learned that principle photography has begun for Star Wars Episode VII directed by JJ Abrams. They posted the image to the left with a tweet that simply said "#dayone". The movie will probably film for most of the summer but thanks to Star Trek, JJ Abrams has mastered how to maintain his secrets and keep sets closed so I am doubting that much info will leak about the movie or its plot.
