Iron Man just keeps looking better and better with every bit of news and image that comes out.
The above image was released to USA Today and is the first official picture of Downey from the film. I'm WAY happy that they selected that particular image since they've been kind enough to show us the character wearing the electronic chestplate that keeps Tony Stark alive. They did a nice job on that, plus notice the beginnings of the Iron Man Mark I armor helmet.
Robert Downey Jr. is turning out to be an excellent choice for the role. He's got the personal history and the gravitas to pull it off and I'm overjoyed that they didn't go with some 26 year old actor for the role. :-)
