Though I'm not a fan of Robert Downey, Jnr, credit to his choice of role in reprising the Iron Man character, this is a fantastic sequel to what was already shaping as a fresh and energetic franchise. Here he does battle against an eccentric Russian scientist Mickey Rourke (!), who's developed a competing manned drone with which his financial backer (Rockwell) hopes to overcome the Iron Man brand, flailing amid the deteriorating reputation of its creator whose rock-star lifestyle is waning on the authorities (a case of art imitating life to some extent).

Paltrow and Cheadle reprise their roles, Paltrow now firmly in the frame as the brains behind the suit of brawn, whereas Cheadle, now without a suit of his own, is somewhat subdued by comparison. Clark Gregg once again makes for an amusing FBI agent, Scarlett Johanson is there as a double agent, and there are small roles for Garry Shandling, Kate Mara and John Slattery. Samuel L.Jackson pops in again to deliver mystical sermons on saving the world, becoming a better super hero etc.

If you enjoy the sarcastic, dry-witted dialogue and the straight delivery combined with explosive special effects then this comic-strip film should appeal. It's just as good as the original (in my opinion) and though starting to become a little self indulgent in parts, isn't yet too self aware. Certainly the best of the current slew of comic book re-imaginings.
