In the final part of an interview with StarWars.com on The Clone Wars, Dave Filoni shared details about wrapping up the series, giving some hints about the bonus material, and having George Lucas as a mentor in creating Star Wars. He discusses concluding season five with Ahsoka’s storyline, and his sense of guardianship over characters from the series. When asked about the bonus material (which were episodes in production for a sixth season), he mentions:
When you look at level of importance to wrap things up for fans, I think that two story arcs that fans will get to see are really, really important for the overall Clone Wars story. So I’m very glad that fans will get to see them in their completed form.
It’s not like all of the bonus material that comes out was planned on really answering things for fans. It’s more, “This is where we were headed,” and the Yoda story arc [announced on Twitter] definitely gives a sense of closure. One of the story arcs, which is very short, is not essential to the overall story but it is a nice final showcase for one of the prequel characters.
Building on Filoni’s comments about the two story arcs, Pablo Hidalgo clarified via Twitter the bonus content is more than just these two arcs.
In the interview, Filoni also discussed moving onto Rebels and being the public face of Star Wars storytelling, reiterating about the new show: “I know some fans just see Rebels as an extension of Clone Wars, but it’s not. It’s an entirely different thing with a different feeling and a different vibe.”
