Okay, so the next question is...characters. Can we glean anything from the picture that's been circulating? Remember it is a script reading so their position might say something about their interactions with those nearby.
I'm guessing its pretty obvious Daisy Ridley is the daughter of Han and Luke based on the fact she sits right between the two actors.
What about the three actors at the top of the photo? Boyega, Oscar Isaac and the weird looking guy Driver. They could be friends. They seem more like friends and allies than enemies for some reason.
Lucas, Carrie Fisher said, cast Ford, Hamill and herself to type. Granted, Abrams isnt Lucas so it could be completely inconsequential how Lucas cast his actors. What does anyone know about these actors and the type of characters they play? I saw a clip of the funny looking guy Driver....he is actually pretty funny in a cynical way...I dont think he is the villain.
