I AM LEGEND is one of my very favorite films.
I’m really excited!
I know rumors were going about in 2008 of a sequel or prequel that never happened. This article was posted this week.
To clear up the death, Neville did die at the end of the theatrical version of I AM LEGEND. The theatrical ending was the reshot version. The alternate ending (where he lives) was actually the original ending (and the MUCH better ending since it gives the rest of the story purpose).
They didn’t use the original ending, and reshot a new ending for the theatrical release because Will Smith accidentally let slip the ending in an interview.
So to put it simply, the theatrical ending (where he dies) is actually the alternate ending.
