I guess this is as good a place as any, according to this guys cast listing, he will be an Ice Giant in Thor 2, assuming this is not a mistake and he's actually a Frost Giant that is. I suspect he is an Ice Giant though because it would seem he's not as bulky as the Frost Giants were in Thor 1, so it seems like the Ice Giants may be taller on screen with effects but on the skinny less muscular side.
so what are you expecting the Ice Giants to look like in thor 2? What do you think their place in the movie might be? Do you think Ymir will have a cameo?
