It is also worth mentioning that it is well documented in early interviews with Lucas himself ,that he planned to pass that proverbial baton off to other directors as the series progressed and he did hire other writers to flesh out the vague story ideas he had going forward , such as the late Leigh Brackett on the first draft of Empire and hiring Lawrence Kasdan to write the screenplay for that movie , Kasdan also had a big hand in writing The Force Awakens as well as Solo.And Lucas was not really even at the Helm for Empire,which is widely considered the best film in the saga .He was mostly hands off except for a few set visits and a bit of editing.Then of Course ,there are the contributions of Marcia Lucas , Willard Huyck and Gloria Katz to the original 1977 film to consider.
