Ever-eclectic director Jon Favreau, who briefly pops up onscreen as a Stark minion, maintains a brisk but not frantic pace, and, in concert with lenser Matthew Libatique, production designer J. Michael Riva and the first-rate visual effects team, has made an unusually elegant looking film for the genre.

Downey plays off his own bad-boy image wonderfully. The writers give him great lines to work with and ditto that for his Girl Friday, Gwyneth Paltrow's Pepper Potts, whose own svelte lines cannot be improved on.

Loyal assistant, Pepper Potts, isn't much of a part, but Gwyneth Paltrow is a presence. She stands around looking amused and flabbergastingly pretty, slinging wisecracks with serene aplomb.

Iron Man, too, is something that people will see regardless of the reviews, but here is the point: Where Michael Bay (Transformers) has mastered a kind of sensory-assaulting pop art, Favreau is a born storyteller who engages the audience's imagination rather than crushing it in a tsunami of digital noise.

All praise to acting dynamo Robert Downey Jr., who brings so much creative juice to the party that Iron Man achieves instant liftoff.
