Oh of course not. Just something to point out and discuss.. cuz I've seen people make the comment that the silver colored cannons are wrong so that's why they added the copper coloring. But in reality THAT'S wrong, at least in terms of "screen accurate". Because on-screen the cannons are depicted as silver, as seen in the DVD movie stills I captured and posted.
Posting the ADI book pics and using that as proof is actually strange as well because by that same thinking, all the black & white Marv statues from "Sin City" with the white bandages are wrong because the "behind the scenes" pics clearly show the bandages were actually NEON PINK.
So as far as "screen accuracy" the white bandages are correct. But if you're going by "behind the scenes" pics and using that as definitve like the one Elder Pred posted of the hand held plasma cannon from the ADI book (i.e. what you don't actually see on screen) then all the statues of Marv should've had Neon Pink bandages. lol.
