Forgot to mention: one of my favorite things was the rogues' gallery they cast as the "World Council":
Evil Widmore from LOST
The Indian dude from the subway station in The Matrix
The hot chick from American Werewolf in London
Actually Jenny Agutter was a member of the World Security Council in Avengers as well - so it was nice to see that level of continuity.
What I was wondering is whether or not the "in shadows" council member played by Powers Boothe in Avengers - was that supposed to be the character that eventually became Alexander Pierce (Robert Redford) in CA2? Or a totally different character? And if a different character, he seemed to be the head of the council in Avengers, why was he replaced?
The other two guys could easily be re-casts of the similar council members from Avengers (just look at the cast lists in IMDB and you'll see what I mean).
