The 2007 loose film adaptation (and only one to bear the name) of Creator/RichardMatheson's novel ''Literature/IAmLegend''.

Creator/WillSmith plays virologist Robert Neville, who is immune to a man-made virus originally created to cure cancer. He works to create a remedy while defending himself against the virus' victims, who turn into hostile mutants.

With its release came four short animated movies which tell unrelated side stories about the rest of the world.

----
!!This film provides examples of:

* TheAloner: Dr Neville.
* AllThereInTheScript: The recurring Darkseeker with a grudge against Robert Neville in the film is called the "Alpha Male".
* AndThenJohnWasAZombie: The DVD short "Shelter".
* ArtisticLicensePhysics: The main spans of the Brooklyn and Manhattan Bridges are destroyed but the back spans remain intact with main cables in tension.
* BadassAndChildDuo: Anna and Ethan are a rare {{Gender Inverted| Trope}} version. While we don't see her fight much, the two of them came to New York from Maryland, across a wasteland infested with [[OurVampiresAreDifferent Darkseekers.]] The two of them were from the same group of refugees, and survived by dint of being immune to the airborne strain of the virus.
* BigApplesauce: As noted on that trope's page, the setting was moved because the visual impact of an empty New York is more effective than Los Angeles, the book's setting.
* BigWordShout: Neville roars "'''''DIEEEEE!'''''" as he [[DrivenToSuicide launches a grief and rage-fuelled attack]] on the Darkseekers in the wake of [[spoiler: Sam's death]].
* BittersweetEnding: [[spoiler:Neville kills himself to allow for the survivors' escape. It's implied that they managed to create the cure afterwards.]] Then again, like FocusGroupEnding below shows, it was not like that originally.
* BoobyTrap: Dr. Neville's zom... er, infection victim traps. The Darkseekers eventually learn to set traps themselves.
* CatapultNightmare: Averted; Neville wakes up from a nightmare by quietly opening his eyes, as a normal person would do.
* ChewingTheScenery:
-->"FRED? WHAT ARE YOU DOING OUT HERE, FRED?"
* ContaminationSituation: Sam, the dog, is infected with a virus that turns [[spoiler:her into one of the mutants. Robert Neville has to strangle his her before she fully turns and tries to kill him.]]
* CoolGun: Neville's rifle; a Colt Law Enforcement Carbine with an [=ACOG=] scope and [=PentagonLight=] [=MD3R=] flashlight.
* CosyCatastrophe: Robert Neville lives in relative peace and luxury in his house, even playing golf and browsing through video stores.
* CrazyPrepared: Dr. Neville, going home at night and also [[spoiler:blowing up his house]]. He also keeps a rifle in an umbrella stand, and hides weapons [[spoiler:including the grenade in the finale]] in random drawers throughout his house.
* CreepyDoll: Well, Creepy Mannequin anyway: If you watch very closely, when Neville sees Fred out in front of Grand Central, Fred's head turns slightly to look him in the face.
* CureForCancer: The start of the zombie apocalypse, as it was a viral injection that would kill cancer cells. Unfortunately, it kills living cells, too. And then brings them back...
* DifferentWorldDifferentMovies: A billboard in the abandoned Times Square has a ''ComicBook/SupermanBatman'' logo. A "World's Finest" or Batman Vs. Superman film was in talks at the same time as this film, but fell through, so this reference was all we got...[[http://www.comingsoon.net/news/movienews.php?id=106748 until 2015, that is]].
* DramaticSitDown: Robert Neville has a moment like this after his dog is infected by the vampire disease and he puts it down. The dog was only companion for three years during the [[ZombieApocalypse vampire apocalypse]]. The following shot is of Neville sitting in his car after burying the dog's body and blankly staring at the now empty passenger seat. He almost commits suicide when two unaffected survivors show up and help him.
* EvilBrit: Averted; Dr. Krippen didn't ''mean'' to create a virus that nearly annihilates the human race.
* EvilStoleMyFaith: When Anna speculates that her coming to New York to find Neville is some part of God's plan, Robert launches into a furious tirade that given everything he's seen since KV got loose, there can be no God.
-->'''Robert Neville''': God's plan?! All right, let me tell you about your God's plan. There were 6 billion people on Earth when the infection hit. KV had a 90 percent kill rate; that's 5.4 billion people dead. Crashed and bled out, ''dead''. Less than 1 percent immunity, that left 12 million healthy people like you, me and Ethan. The other 588 million turned into your Darkseekers, and then they got hungry, and they killed and fed on everybody. ''Everybody!'' Every single person that you or I has ever known is '''''DEAD!!!!''''' Dead! There is no God! There is no God.
* {{Flashback}}s: Tells how [[spoiler:his family died and why he's stuck in New York]].
* FocusGroupEnding: Infamously so, ruining most of the {{Foreshadowing}} and creating a few {{Plot Hole}}s. Originally, [[spoiler:Neville would have realized that the infected are intelligent, and just want to take back the flock member he has in his captivity in order to test his cure. A shocked Neville allows to them do this, after which the infected leaves without causing further trouble. The whole event makes Neville [[HeelRealization start to question his own morality]], when the implications of what he has done to develop his cure dawns on him.]] In the final version of the ending [[spoiler:the intelligence of the infected is just implied, but ultimately ignored, and Neville makes a HeroicSacrifice to help the others escape with his cure]]. The original ending was eventually included as bonus material on the DVD, where it was named the "controversial" ending.
* {{Foreshadowing}}: Neville captures an infected female with a snare trap, and the Alpha of the pack leaves the dark to glare at Neville before walking back into the dark. Neville takes it as a sign that they've lost their self-preservation skills. The Alpha later shows up, having caught Neville in the exact same type of snare trap he built with a pack of dogs, [[spoiler:hinting that the infected are intelligent, and that the Alpha wants the girl back]].
* GenderReveal: Right in the middle of the TearJerker that is [[spoiler:Sam's death]], Neville uses her full name for the first time, somehow making the whole thing even more devastating:
--> '''Neville:''' [[spoiler: "Samantha..."]]
* GhostCity: New York. The DVD extras show Hong Kong also became this.
* GunsDoNotWorkThatWay: The [=ACOG=] scope on Neville's rifle has a reticle from a Russian PSO-1 scope as used on the Dragunov sniper rifle.
* HeWhoFightsMonsters: Done more subtly than in the novel, [[spoiler: the camera pans to the dozens of infected that Neville killed doing experimentations on when he does the same to the one he's currently working on. Anna even looks on with [[WhatTheHellHero horror]] when she sees the failed experiments.]]
* HellishCopter: [[spoiler: The fate of Neville's family, [[HopeSpot as they were being evacuated from the city no less]].]]
* HollywoodAtheist: Neville refuses to believe in God due to the events after the outbreak.
* TheImmune: Dr. Neville.
* ItCanThink: The Darkseekers are very intelligent, replicating Neville's traps as well as [[spoiler: taking out the defense floodlights around Neville's house.]]
* ItIsDehumanizing: Anna watches Neville experiment on a captured zombie, and asks whether what he's doing will "cure her." Neville responds "Actually, it will probably kill it," with the second "it" slightly emphasized.
* TheLastManHeardAKnock: Dr. Neville meets up with the other survivors.
* LivingProp: Ethan. He has no lines and never does anything other than not die. Only thing that he's used for is Neville showing how much time he's had on his hands when reciting ''WesternAnimation/{{Shrek}}'' by heart.
* LonersWillStayAlone: Neville is lonely for reasons evidently unrelated to his social skills, but he exhibits many of the characteristic traits of the more extreme examples of this trope, such as making imaginary friends out of puppets.
* MadScientistLaboratory: Dr. Neville's basement lab, which requires several generators to power and is quite impressive for a post-ZombieApocalypse lab.
* ManlyTears: [[spoiler: Neville sings Bob Marley's 'Three Little Birds' to Samantha as he holds her in his arms. When she begins to attack him, he strangles her and weeps. The next day, he walks into the video store and breaks down when he finally talks to the girl-mannequin.]]
-->"Don't worry... 'bout a thing... 'cause every little thing, is gonna be alright..."
** Also:
--->"I... I promised a friend I would say hello to you today... Please say hello to me... Please say hello to me..."
* MayorOfAGhostTown: Neville, more or less.
* MindScrew: Fred the Dummy. Neville is less than pleased to see him outside the store.
* MyGodWhatHaveIDone: Similar to the HeWhoFightsMonsters entry, it's rather subtle in the original ending; [[spoiler: after returning the mate to the alpha male, Neville looks over at the wall containing pictures of past infected who died in his experimentation.]]
* NeverTrustATrailer: The commercials suggested the film was an action thriller instead of the slow horror-drama it is.
* OhCrap: Anna and Neville when they realise the Darkseekers managed to track them home.
* OurVampiresAreDifferent: The infected creatures. They display characteristics that are a cross between vampires and zombies. Their skin, which is pale, is harmed by sunlight, they're incredibly fast and strong, they have a decayed appearance, are hairless, and spend most of the film acting like stereotypical fast zombies. [[spoiler:Except that they have rudimentary intelligence and feelings for each other...]]
* RaceLift: Neville is black in the film.
* RidiculousFutureInflation: Gas costing $5.95 a gallon.
* SanitySlippage: Mostly happens before the "current" time of the movie, though it gets really slidy after [[spoiler:Neville is forced to [[DespairEventHorizon mercy-kill his only companion, the dog]].]] Talking to your pet? That's fairly normal even now. Talking to a mannequin? A little odd. Expecting, nay, ''begging'' it to talk back? (See Manly Tears) Yeah, you're pretty far gone. Spending three years as the only uninfected human in New York City, hell the entire world, [[spoiler:or so he thinks,]] will probably make you a little unstable. There's also the fact that [[spoiler:even when reunited with other humans]] he still seems a little broken. Among which being the refusal to think that other humans even ''could'' be out there or that the infected aren't the mindless beasts he thinks, despite ever-growing mountains of evidence otherwise, and going blank as he spoke along with the movie ''WesternAnimation/{{Shrek}}'' in a way that would make Pavlov proud.
* SawStarWarsTwentySevenTimes: The number of times is not specified, but Neville has seen ''WesternAnimation/{{Shrek}}'' enough to know the dialogue by heart.
* SamusIsAGirl: [[spoiler: Sam the dog is actually Samantha]]
* SceneryGorn: Much of the movie dwells on the spectacle of New York returning to nature and the traces of the desperate last days e.g. the blown bridges. The portrayal of the vegetation, contrary to popular belief, is actually quite conservative. In reality it's likely that the speed of New York's reclamation by nature would be much ''more'' thorough by three years later. As one example, if such an extinction were to occur there would be no one to man the water pipes underneath the city, the subways would flood within a week and almost all of the surface streets would cave in from the erosion. As a rich pool of nature right in the middle of Manhattan, Central Park would also increase the rate of reclamation.
* ScienceIsBad: The vampire/zombie plague began as a cure for cancer.
-->'''Neville:''' God didn't do this, ''we did!''
* ShootTheDog: Literally. Alright, literally figuratively: [[spoiler:More like "Choke the (Zombie) Dog".]]
* ShoutOut: The aforementioned Batman-Superman billboard.
* SoleSurvivingScientist: Dr. Robert Neville is about as alone as you can get.
* StakingTheLovedOne: [[spoiler: Sam]]
* StrappedToAnOperatingTable: Dr. Neville uses steel manacles to do this to a vampire while searching for the cure. Several, in fact.
* SurvivorGuilt: So, so much.
* SyntheticPlague: The mutated cancer cure [[HatePlague rage virus]].
* ThereIsAnother: [[spoiler: A whole village of them, in fact]].
* UnstoppableRage: After he is forced to MercyKill Sam, he goes on a RoaringRampageOfRevenge against the infected, [[TakingYouWithMe hoping that he dies as well.]]
** The Alpha Male is in one of these as the Darkseekers break into Neville's home, smashing aside those of his own pack that get in the way to get at Robert. [[spoiler: Justified, as in the original ending, [[LoveMakesYouCrazy the Alpha considers Neville to be holding his mate hostage and desperately wants her back]].
* TheVoiceless: Ethan never says anything throughout the movie. Well, he does say "It's cold." at one point.
* WhereItAllBegan: A variant; Dr. Neville refuses to leave New York City because it's ground zero for the virus, and he will not let it win in his backyard.
* WorthlessYellowRocks: Dr. Neville finds himself walking over a fortune in bank notes, abandoned on the floor.
* WorthyOpponent: Dr. Neville seems to consider the virus itself to be this. While documenting the results of his latest failed attempt to cure the virus, he comments on the elegance of its design with what is clearly a tone of grudging respect.
* ZombieApocalypse: With Vampire Fast Ghouls that aren't really vampires. Close enough, even if the film is NotUsingTheZWord and instead calls them "dark seekers".
