This trailer almost makes me too giddy to even think straight, let alone to write about it. I mean, come on: It's a dream come true for anyone who's followed Robert Downey Jr.'s career -- not to mention his life -- to see him get a plum role like this one. Not because he necessarily deserves it, but because he's certainly worked for it. Usually superhero roles come to you earlier in life, but this is no typical superhero movie. The trailer starts with rock music in the desert -- looks like it must be Iraq, or some other desert nation in which our troops are stationed. Downey Jr. is a genius weapons designer/arms dealer over there to demonstrate and sell some new technology. All does not go well, though, as he is taken prisoner, presumably so that he can build them some sort of amazing weapons. Instead, he builds himself a magical mask that makes him a superhero, helping him escape. He gets back home, but don't worry: He isn't ready to stop being a superhero. He keeps designing cool stuff for his alter ego, and gets to say cool superhero lines like, "Yeah ... I can fly," in the most nonchalant manner. There's also a seriously evil-looking Jeff Bridges, who's both bald and bearded. I'm not sure what it is about transporting the hair from his head to his chin that makes him the scariest thing ever, but it does. So, Iron Man: He's totally a new breed of superhero. And the best part? He wears armor instead of tights, so he doesn't have to overcompensate in order to look truly kick-ass.
