Caymen, it seems that most of the 9 bonus minutes was spent on extending the scene in the "space jellyfish" forest, a scene that was meh imo.
Interesting you should mention that about actors names, because I don't remember the characters' names, for whom I gave the actors names, as they were barely mentioned in the movie.
Stephen Lang plays the Colonel, the best char, who has some weird name that was rarely mentioned. Weaver was the head scientist chick.
I was really hoping that the bonus footage would be Humanity bombing the Space Indians from orbit, with references to the scene from Apocalypse Now..but sadly that was a pipe dream, wasn't it?
(But we all know it is going to happen, Unobtanium is a room-temperature superconductor. We're not letting that go)
...sorry, getting into Avatar rant-mode again.
