May 2, 2008 -- Hollywood has unearthed an unlikely weapon of mass destruction: Robert Downey Jr. In "Iron Man" (* * * out of four), Downey's likably snide playboy character is cut from the same anti-hero cloth as Johnny Depp's Jack Sparrow -- and he's primed to annihilate the competition this weekend.
Downey's Tony Stark, the weapons magnate who creates and dons the high-tech suit, is charismatic, sarcastic and witty. And he finds a way to fuse swaggering confidence with soulful self-deprecation, transforming a comic-book hero into an offbeat and complex character.
The billionaire inventor's family has been in weapons manufacturing since the A-bomb, but he never did much soul-searching. His worldview is radically altered in Afghanistan after being taken prisoner; he builds the super-suit and vows to do good.
Jon Favreau ("Elf," "Swingers") directs a strong ensemble cast, including Jeff Bridges, who cleverly plays Stark's right-hand man; Terrence Howard, Stark's nicely underplayed military pal; and Gwyneth Paltrow, just right as Stark's assistant, Pepper Potts.
The extra heft brought to their cartoonish characters and the special-effects action make "Iron Man" entertaining and fun — though the second half has less snap, and a pivotal fight sequence between Iron Man and a nemesis is predictable.
Along with the expected Marvel comic-book feats enacted with expert computer-generation imagery, the film blends elements of "Transformers" with James Bond movies.
As Stark soars around in his titanium alloy outfit, aiming fireballs with perfect precision, he is as potent a figure as Superman. He's as rich as Bruce Wayne with an extra dollop of science-guy nerdiness, finished off with a heaping dose of snark. Iron Man's biggest strength is that the fantastically armored suit doesn't overpower the intriguingly flawed character encased within.
