Forum:KB:Poggle the Lesser

In the Behind the Scenes section in Poggle's entry here on Wookiepedie it says: Poggle the Lesser was voiced by Ernie Fosselius in Attack of the Clones. And in the entry of Attack of the Clones the movie:Poggle the Lesser … Marton Csokas. Even Marton Csokas got his own entry here. I can find no other sources to this information. And more on the cast lists. The Revenge of the Sith the movie entry tells us about a character called Gilgamour being portrayed by some Christopher Rodriguez (in red letters). I can't find anything about this character anywhere else. So where does all this information come from? Ok if Csokas was meant to portray Poggle at some point, but to still have this information here?
