Didnt you hear Kubak? DONT TRUST IMBD! Now, that doesnt mean Mr Zurkon cant be in the game or movie, after all he WAS one of the weapons shown in the teaser trailer.
Ah, someone listens to me Yeah, Mr. Zurkon is very probable due to his popularity, but the info on IMDB is no confirmation - anyone can edit this site. It used to list Tara Strong as Talwyn in ItN (thought Ali Hills played her there) and the Zoni in FFA (even though they weren't in the game at all) - basically, fans add a lot of fake information before the release of the game/movie there. So far the only characters confirmed for the movie are Ratchet, Clank, Qwark, Drek, Nefarious, Galactic Rangers and all the minor characters seen in the trailer. Lawrence and Mr. Zurkon are yet to be (or not to be) confirmed.
