Warner Bros. has decided they'd like to add a second film to the I Am Legend catalog, and, after someone explained that Will Smith dies at the end of the last one (spoiler!), they've decided it will be a prequel. From Variety:
The plan is for Smith to reprise his role as scientist Robert Neville, with Francis Lawrence returning to direct. Akiva Goldsman and his Weed Road banner will produce with James Lassiter, Smith’s partner in Overbrook Entertainment.
The studio has set D.B. Weiss to write a script that is based on a detailed outline that was hatched over the past few months by Smith, Goldsman, Lassiter and Lawrence.
The prequel will chronicle the final days of humanity in New York before a man-made virus caused a plague that left Smith’s character the lone survivor among a mutated mob in the city.
If the prequel does well, will there be a third film, where we go further back, to an even less relevant time and story? Because I'm hoping we can keep going back, eventually building a bridge from I Am Legend to The Fresh Prince of Bel-Air where the entire plague was in some way caused by the Carlton Dance.
