I’m Legend is a Sci-fi Movie based on a Medical theme. How a mutated airborne infective virus can cause unimaginable casualty has been shown.
In December 2009, military virologist Lieutenant Colonel Robert Neville (Will Smith), lost his wife Zoe (Salli Richardson) and daughter Marley (Willow Smith) in a helicopter accident during the chaotic quarantine of Manhattan as K.V. (Krippen Virus), a genetically-engineered variant of the measles virus meant as a cancer cure, mutates into a lethal strain and spread worldwide, killing 5.4 billion people (90% of humanity). In September 2012, Neville is left as the last healthy human in New York City. Of the 600 million survivors, only 12 million people were naturally immune to the virus. The rest degenerated into bald, pale, aggressive beings referred to as “Darkseekers,” who hunted down the immune humans as prey. The “Darkseekers” are so-called for hiding in buildings and dark places during the day due to a painful intolerance to UV radiation. The infected exhibit increased speed, agility, aggression, and strength. These abilities stem from an increased metabolic rate, which also consumes the infected with an overwhelming hunger which makes them resort to cannibalism. Despite their primal behavior, the Darkseekers seem to retain some basic problem-solving intelligence, animalistic cunning, and the capacity to organize themselves.kly running out of time.
The cure is found but not without sacrifice.
