How did I Am Legend end?

I Am Legend is set in a post-apocalyptic world in the backdrop of a zombie invasion that has left Neville the last man standing on Earth. Neville is immune to infection and is trying to find a cure using his antibodies and testing on infected human subjects he keeps locked up in his lab for that purpose.

Almost on the brink of insanity with no one to talk to and only his dog to keep him company, Neville tried to rejuvenate humanity and end his loneliness. He keeps failing, and the situation gets worse when his dog is bitten by zombie hounds and has to be euthanized. Without his sole companion, Neville feels he has nothing to live for and heads out into the night on a kamikaze mission to take as many creatures with him as he dies. That is when he meets another survivor and her son, who rescue him and take him to a survivor colony.

Anna’s arrival is a hope for redemption, but not quite. They triggered a mega zombie showdown in light of which Neville handed over to Anna his latest antidote, which seemed to be working, and then sacrificed himself so Anna could escape.

What is the alternate ending?

The original ending of the sci-fi film dismisses any possibility of a sequel.

So what makes the sequel possible? An alternate ending. In the director’s cut, alternate ending of I Am Legend, the alpha male zombie who set the trap for Neville makes the sign of a butterfly through the glass to indicate the butterfly tattoo the female zombie (whom Neville had kept prisoner) has. Neville finally realizes that these creatures have their own relationships and community, and the woman was the alpha’s partner. Neville sacrifices himself so that Anna and her son can escape, and he is left at the mercy of the alpha.

Understanding the alpha's emotions, he apologizes and returns the captured female, and the alpha shows Neville mercy by not killing him. Neville lives in this version, and it also makes a sequel possible.
