Lifestyle | Will Smith Legend Science a Little Shaky The idea of this killer virus is 'far-fetched,' says one expert By Laurel Jorgensen Posted Dec 19, 2007 11:38 AM CST Copied Actors Will Smith and Jada Pinkett Smith arrive at the premiere of "I Am Legend" at Madison Square Garden, Tuesday, Dec. 11, 2007, in New York. (AP Photo/Peter Kramer) (Associated Press) A man-made virus has turned people into mutants and killed off the rest. Downtown New York City looks like a jungle, and the only man left on the planet is trying to reverse the plague using his immune blood. So how realistic is the premise of Will Smith’s new blockbuster I Am Legend? Surprise! Not very, experts tell Popular Mechanics. While a wildlife expert says animals and plants would certainly settle in a post-apocalyptic NYC, one of the world’s top virologists says the virus storyline is “pretty far-fetched.” Viruses don’t mutate and become airborne, and the main character’s attempt to find a cure in his own blood “doesn’t make any sense,” he says. As for the mutants: “This is Hollywood. That’s all I can say.” Read These Next New Fox star, 23, misses first day after car troubles.
