I had to cut a matte around them, though, since it would slightly darken Tack due to his grey shades. (BTW, what's with his hands being so huge in that shot?)
What's funny is that you can tell it was inked and painted in Korea... because they did the same thing to black characters when the Looney Tunes were colorized in the 1960's. One cartoon has a gag with a ghost in blackface and he's in purpleface instead.
Ah, political correctness...
