Xoanon here,
Despite recent rumors Wi Kuki Kaa has not been casted or even considered by PJ et all.
TheOneRing.net put in a call to Kuri Kaa himself and asked him about the rumors of him playing Ghan-buri-Ghan, a chieftan in Lord of the Rings.
‘First I’ve heard about it’
hmmm, either he’s got a very mysterious booking agent. Or it’s another attack from the rumor mill again. Well, you’ve heard it here first.
