I finally got to watch the highly satisfactory Guardians of the Galaxy, and I think I've caught a fairly serious factual error.
Rhomann Dey: He said that he may be an... "a-hole". But he's not, and I quote, "100% a dick".
Nova Prime Rael: Do you believe him?
Rhomann Dey: Well, I don't know if I believe anyone is 100% a dick...
It appears that news of the existence of the Dick on the right (naturally) has not made its way to Nova Prime; they probably don't get Faux News.
Lucky bastards.
