I Am Legend (2007) starring Will Smith, is a zombie movie. It focuses on U.S. Army virologist Lt.Col. Dr. Robert Neville, who is alone in an empty New York City three years after a mutating virus exterminated the human race.
The virus changed all that it infected into savage, flesh-eating killers -- who then turned on the uninfected in a feeding frenzy. These zombies aren't like those in the George Romero movies. They are much faster, stronger, and agile than normal humans. They are also semi-intelligent, and even cunning, at times. They are, however, extremely sensitive to light, and therefore hide in the shadows during the day. The night, however, belongs to the walking dead.
Accompanied only by his dog, Neville struggles in his underground laboratory to find a cure that will reverse the virus and return the zombies to their normal, human state.
Will Smith's performance was impressive as the failed messiah -- the man who was supposed to save the human race from the virus and who still clings to the faint hope of "fixing" the problem. It is the first movie, to my knowledge, which features Smith with gray hair. The movie will help Smith age as an actor. Some actors, such as Michael J. Fox, are never able to move past youthful roles, but Smith shows the potential to do so. He's come a long way from The Fresh Prince of Bel Air.
I have written a spoiler on this page. I have written it only because there is a scene in the movie so ghastly that had I known that it was present, I would NEVER have taken my wife with me. Be warned.
