Is the guy on the other side of the engine from Han and Leia from the Polar Express? And the guy diagonally up and to the right of the droid with the bloody arms... for some reason he makes me think of Jack Dalton from MacGyver.
That isn't Palpatine next to the guys all in red, in the lower left corner, is it? And would the guy in front of him be Admiral Thrawn?
I know other people have spotted Waldo and the TMNT, but I haven't.
