I like the addition of Scarlett Johanssen but man Mickey Rourke is awful imho in the trailer, and towards the end Robert Downey pretty much looks like he is phoning it in. And he really never played Stark in the first film really just a charicature of a Republican imho. I am a big fan of the comics and i never pictured this actor while reading them.

First one was a great action flick but did not really storywise do anything that has not been done before, although the cgi was the main selling point just like star trek 2009. Dark Knight was a much better film despite Batman pulling a George Bush.
