So where in your bountiful reasearch do you have a signed affidavit from the artist(s) who drew and colored the comic adaptation that they saw the entire movie from begining to end ALONG WITH definitive character designs for every single Clone Trooper in REVENGE OF THE SITH? And of course, corroborating evidence from the people who approve all of these materials at Lucas licensing before they go to press? Oh wait, you don't.
OWNED. So totally OWNED.
