Per a source close to the production and casting of Star Wars, Disney is planning to start shooting the new movie in London. Another bit of information told to The Daily SuperHero is the next Star Wars movie will indeed be an original tale that is not taken from any novel, comic book or graphic novel story that has already been published. Interesting note about this bit of info is that Star Wars video games were not mentioned, so there's a slim chance something from one of the games could be in the new film. But that is pure speculation on my part.
No actors were mentioned as being officially signed on for the movie, yet. However, our source said that Abrams loves the idea of having Luke Skywalker, Han Solo, Princess Leia and Lando Calrisson make some kind of appearance or have a small role. In other words, the script is still being worked on by Abrams and screenwriter Michael Ardnt.
Some may say this info is garbage since it has not been confirmed by Disney or Lucasfilm, but the position the source has leads The Daily SuperHero to believe this info is as solid as it comes for the next Star Wars movie.
