Directed by: Francis Lawrence
Starring: Will Smith, Alice Braga, Salli Richardson-Whitfield, Charlie Tahan
Continuity mistake: At the end of the movie, when Neville is behind the glass and he is thinking and all the sound goes away, you can see the bite mark that the zombie gave him. While the shot is changing between him and the zombie, you can see the bite mark change sides of his shirt.
Factual error: The grenade Robert Neville uses at the end of the movie has a blue and brown colored lever. This feature is only used on the M69 practice grenade and not the real M67. The lethal grenade lever is completely green.
Neville: God didn't do this. We did!
Trivia: Smith tries to explain to the woman who Bob Marley is by singing a part of the song "I Shot the Sheriff." He also sang this part of the song (with a similar voice imitation) in his role as Will in one of the episodes from the series "Fresh Prince of Bel Air".
Question: The question is if all the bridges and tunnels to Manhattan are destroyed, how does one drive from New York to The Colony in Vermont? How do Anna and Ethan drive to Manhattan to meet Robert Neville in the first place?
Answer: In the alternative ending Dr.Neville, Anna and Ethan are seen driving a car over a bridge that wasn't destroyed. The army would need to leave a entry/exit point, but it would have been heavily guarded until everyone died.
