In this mini-doc, you get a look at the design and creation of the fearsome Death Troopers, the elite Stormtrooper unit favored by Ben Mendelsohn's Director Krennic. They're described here as being like the "Seal Team 6 version of the Stormtroopers," and boy are they scary -- tall, elegant, scary. While the clip is brief, it does highlight a tidbit that I hadn't even heard before: that their design was based on a sketch by Ralph McQuarrie, one of the designers for the original series whose distinctive look has been appropriated recently for things like "Star Wars Rebels" and even "Star Wars: The Force Awakens." It goes to show you that a good idea never dies it just surfaces decades later."Rogue One: A Star Wars Story" is on Digital HD and Disney Movies Anywhere this Friday, and on Blu-ray/DVD April 4.
