Star Wars: The Clone Wars Supervising Director Dave Filoni took some time to chat with Yahoo TV regarding the return of Darth Maul in the Season 4 finale. We have a short excerpt for you below that touches on Maul's spider legs but make sure to click here for the full read.
"The spider legs were 100 percent George. When hashing these stories out, we do it all together in a writers' room. It includes six writers, George Lucas, and myself. George will say something like, "I want to do this story where we bring Darth Maul back." Then we all politely argue the different points of why we should or shouldn't. After that we outline everything together. George has a very heavy hand in all that of course."
