"I Am Legend" Prequel for Smith?

"I Am Legend" was not one of my favorite movies of the fall season last year. It wasn't bad, it simply wasn't everything it was built up to be. It was a loss of potential and waste of character study. Although, it did have a few scares and Will Smith was, as usual, stellar. A sequel or prequel is not something that interests me. However, money talks over a barely noticed movie blog and at $584 million worldwide, it was only a matter of time before more information on an "I Am Legend" follow up was announced.

Francis Lawrence, director of the film, recently confirmed that a prequel was in the workshop. Not only that, but Will Smith has communicated a desire to return as well. Currently, Lawrence is working on another story that will develop Robert Neville in a different light.

So where could this go? The creation of the zombie creatures? Everything just before the outbreak-- Because lets face it, everything we really needed to know was shown in flashbacks of the recent film. Would a prequel reveal that much more? Hopefully we'd get to see more of the dog.
