Also thanks for showing me that. I love seeing stuff that got changed over the course of a films creation.
Oh man, you should start digging into the production of this movie. The story is FASCINATING.
Short version- Lawrence Kasdan, the writer of Empire, only agrees to come back for the Disney Era if Disney puts into production the Solo pet project he and his son have been kicking around. Disney agrees, and hires Lord and Miller of Jump Street fame to direct the movie.
Production starts and the tone is completely different than what the Kasdans want. It's a Lord and Miller movie, which is to be expected when you hire those guys. Aiden calls Lucasfilm and expresses his concerns. They shut down the movie and bring in Ron Howard to reshoot 80% of it.
