Matheson's Legend and Its Legacy...

The next major film adaptation of Matheson's novel was the big-budget 2007 film. Though it marks the first time that a film bore the title I Am Legend, the film had more in common with the two prior film adaptations than it had in common with the novel.
It starred Will Smith as Robert Neville, again a scientist who believed himself to be the sole survivor of a global pandemic that turned the infected into violent cannibalistic mutants that have a severe form of photosensitivity. The film attempts to give greater access into Neville's character and shows his life during the day as he takes out old movies from the rental store, converses with mannequins for company,  listening, an to reggae music, and fortifying his holdup. He then spends his nights hunting the cannibal creatures and setting traps for them. During one nightly outing his dog is bitten by an infected dog and Neville is forced to kill it. Now, completely alone, Neville becomes reckless and sets out to get revenge. However, he is greatly outnumbered and only survives when he is, again conveniently, rescued by two human survivors, a woman named Anna and a young boy named Ethan. The three go back to Neville's house where they form a familial bond and where Anna tells Neville of a small group of survivors. The next night the house is attacked and Neville is forced to sacrifice himself, but before doing so he discovers that his experimental cure is working and he gives it to Anna so that she can take it to the remaining survivors.
While the film boasted impressive special effects and some strong acting, it was met with mixed reviews and many criticized the director, Francis Lawrence, who is best known for his visually impressive music videos.
