A couple days ago, we debuted this exclusive clip from the new Star Wars Rebels Season 3 Blu-ray that gave fans a deeper look at Mon Mothma and her story within the larger Rebellion.
Now that Season 3 is available for purchase, Lucasfilm has released two other clips from the special features: a behind-the-scenes for the Sabine-centric Return To Mandalore and a behind-the-scenes on Thrawn.
The Thrawn video has some really interesting insights into what went into Thrawn's look, the casting, and just how involved Timothy Zahn was in the process. Likewise, the feature on Return to Mandalore is a must-watch for fans of Mandalorians both in Rebels and in The Clone Wars. The Mon Mothma clip is part of a much larger feature on the rebellion itself and definitely one fans of the original trilogy will enjoy.
In other words, this is a glimpse into a much larger bonus feature world.
Having personally had a chance to check out the Blu-ray, I can tell you I think it's worth it based on Dave Filoni's audio commentary for "Trials of the Darksaber" alone. The rest is Bantha gravy.
