Hammer hires Vanko to design a better suit than Stark's, the two suit designs go to war, we get half an hour of sensational special effects, and Bob's your uncle. But you also have a niece, sexy martial arts expert played by Scarlett Johansson, who may be more than she seems. The character was named Black Widow in the comic books, never a good sign. Fighting at Stark's side is his comrade Lt. Col. "Rhodey" Rhodes (Don Cheadle); while rocketing through a blizzard of enemy missiles, the two find time to talk. How slow must a missile be moving if your buddy has time to warn you to dodge it?
