I Am Legend (film) [SEP] Possible prequel
Director Francis Lawrence said in 2008 that there would be a prequel and that Will Smith would be reprising his role. The plot of the film would reveal what happened to Neville before the infected took over New York. D. B. Weiss was hired to write the script, while Lawrence was in negotiations to return as director, contingent on a sufficiently interesting story. Smith later discussed the premise, which would have his character and a team going from New York City to Washington, D.C., as they made their last stand against those infected with the virus. The film would again explore the premise of being alone.
