Robert Downey Jr. in Iron Man 3IRON MAN 3

Iron Man 3 begins with narration by Tony Stark, the superheroic multi-billionaire voiced and eventually embodied, as always, by Robert Downey Jr. His tone is steady and somber as he makes ominous pronouncements about the uncertain state of the world and how we each create our own demons and such, but before long, Stark's more expectedly breezy, wise-ass nature takes over - he stumbles over his words and realizes his blathering isn't really going anywhere, and quickly puts a kibosh on the opening address. The whole routine is reminiscent of Woody Allen's hilariously neurotic "Chapter one ... " intro at the start of Manhattan, and immediately suggests that this second sequel to 2008's effects-laden blockbuster will be both deathly serious and happily insouciant. And it is. I'm just not completely convinced, in the case of Iron Man 3, that that's a good thing.
