Will Smith is in another sci-fi novel adaptation, this time I Am Legend by Richard Matheson, which has been adapted twice before. Apparently, a four writer team undertook this adaptation. Either that or two writers adapted a previous two-writer adaptation. Matheson has many stories in the public mind, in part because he worked on The Twilight Zone, in part because authors like Ray Bradbury, Stephen King, and Dean Koontz have praised his work highly. Another adaptation from him, one of a script seen on The Twilight Zone, is coming in the movie The Box. Still another in The Incredible Shrinking Man.
From what I understand of the story, I Am Legend can’t be called a vampire tale, though there are vampires in it. It’s better described as a post-apocalypse story, focusing on a man as a representative of all mankind. Speaking of the Matheson’s book, Dan Schneider says it focuses “on human loneliness. . . Its insights into what it is to be human go far beyond genre.” (Spoiler warning on that link.) It could be a good movie. Probably is a good book.
