Holy crap! I've never noticed that before! I've been too busy trying to read that screen all these years. Is that from Empire or Jedi? Although it would make sense if they simply recycled that shot for Jedi...

And C3PX, there were some Mon Calamari in ROTS. They were the aquatic dancers in the "opera house" scene, but we never got to see them close up. (There is concept art of them out there someplace.) And I think one turned up as a senator in one of the cut scenes showing the future leaders of the rebellion expressing concern over Palpatine's actions.
