in the "Mask of Light" trailer, Vakama says "Trust in the mask, let it be your guide" this means that the mask is supposed guide Jaller and Takua to the Toa of Light. Now, you see someone putting the Mask of light to his face. That must be Taka Nuva!

Nope, that's a Turaga. The hands are not Toa Nuva hands and they look just like Vakama's hands.

i've said this in many topics those hands are black so they must be whenuas

No, I don't think so.... The movie is called; The MAsk of Light... Not: The Toa of Light... So that must be a turaga, or a Matoran or somethin.

I doubt its a Turaga, all the Turaga are behind (or infrotn, depending on how you look at it. So it's probably the ToL, if not Takua

I personally think it is Makuta. Look at the characters in the background and how shocked they are...

Well , notice the stubby hands and fingers , its got to be a Turaga of Matoran , and i DO think Takanuva is in the movie , cuz its about the search for the 7th Toa (Takanuva)
