I Am Legend 2 is finally in the works, and there are several leftover questions from I Am Legend that it will need to answer. It's been over 15 years since Will Smith played Robert Neville, and audiences have been on the lookout for a sequel ever since. The movie ended ambiguously with two drastically different endings, neither of which entirely tied up the story of Earth's fall to the Krippin virus. Now that I Am Legend 2 is finally going to be a reality and it has committed to one of the two possible endings, the continued story can finally be told.
