Interesting follow-up to the Ironman movie, Downey is good in his role.

Rating: Null/10 (2 October 2010)

In the first movie we learn that Tony Stark's company designs and manufactures weapons. But when Tony gets taken prisoner in a foreign land he learns that the enemies are also using his weapons, and that realization gets him to get out of the weapons business. The Ironman suit was developed from the crude version he built while a prisoner to make his escape. He is a very bright and industrious fellow.
Robert Downey Jr. returns as Tony Stark, and as this movie begins we see him called to a federal committee, chaired by Garry Shandling as Senator Stern. They are trying to make the case that the various Ironman suits are in fact weapons, and should be controlled by the US government for homeland security purposes. But Stark insists they are for preventing crime.
Don Cheadle is now the good friend, Lt. Col. James 'Rhodey' Rhodes. Gwyneth Paltrow is back as his assistant Pepper Potts, who clearly longs for more.
Sam Rockwell becomes the first nemesis, as Justin Hammer who competes with Stark, but not very well. His designs just don't work well. But the really bad nemesis is Mickey Rourke as Russian scientist Ivan Vanko, who makes a new kind of suit that threatens Stark.
For me the most pleasant surprise was Scarlett Johansson as Natalie Rushman but really Natasha Romanoff. I've seen her in quite a variety of movies, starting with "The Horse Whisperer" when she was a teenager but never in an action role. Here she cuts quite a nice figure in her skin-tight suit and proves to be quite effective as a martial-arts fighter. Who would have thought??
So what happens in a movie based on a Stan Lee comic? The hero always finds a way to get the best of the bad guys. There is a lot of action, and some tense moments, but in the end Ironman sets things straight.
