Well, the Mount Doom set is repack. I have Gollum in front me from the TTT talking-rock version and it's the exact same face mold. As for Sam and Frodo...it's the figures from FOTR, where they are in the boat. Same arctiulation, same sting, the only difference is the capes.
Blast, I was hoping for a new Frodo....oh well, more money in my pocket, I guess.
