Overview

I Am Legend is a 2007 American post‑apocalyptic action thriller starring Will Smith as Dr. Robert Neville, a military scientist and the apparent last uninfected human in New York City. The story follows his daily struggle to survive, to study the disease that wiped out much of humanity, and to find a cure while facing nocturnal, infected adversaries and profound loneliness.

Background and development

The film is a modern screen adaptation of Richard Matheson’s 1954 novel of the same name and is part of a lineage of cinematic interpretations that includes earlier films. During development it underwent several script revisions and was released in different versions; a theatrical ending and an alternate ending appear on home video, reflecting differing tones and interpretations of the story.

Plot elements and characters

Neville’s routine, scientific work and his bond with a dog are central to the narrative. Encounters with other survivors shift the direction of the plot and raise questions about trust, sacrifice and the nature of the infected beings. The film combines action set pieces with quieter, character‑driven moments to balance spectacle and emotion.

Themes and style

Visually the movie emphasizes an empty, reclaimed urban landscape—familiar city landmarks rendered desolate—to underscore themes of isolation and loss. It juxtaposes scientific inquiry against fear and superstition, exploring what survival means in a changed world. Will Smith’s performance was widely cited as anchoring the film’s emotional core.

Reception and legacy

Upon release, the picture drew mixed critical responses: it was commercially successful and praised for performance and atmosphere, while some critics and fans noted departures from the novel and debated the impact of its alternate endings. The film renewed popular interest in Matheson’s original work and in adaptations of survival narratives.
