Corrected entry: The first evening, Robert seals all windows with huge, thick shutters. But when he wakes up, daylight is shining on him.
New this month Correction: He barricades all the windows and lays down in he tub with his dog and rifle, but he doesn't go to sleep. You can see that he's awake and listening to the zombies noises. He's afraid and has his hand on his rifle just in case they break in. Once the sun comes up, it's safe for him to open a window, take a look outside, and finally go to sleep in his bed. That's why you see him waking up in sunlight, it's just sometime later in the day. You can also see that he dreads the night when he's washing his dog and his alarm goes off. It's not a safe time for him so he has to spend each night in constant fear of attack.
Corrected entry: Hand grenades do not create a massive fireball - even in a lab full of combustible chemicals, the heat from a grenade wouldn't be high enough to ignite them.
Correction: The flash point of acetone is -4 F and the flash point of diethyl ether is -42 F. Both of these could definitely be present. Either of these chemicals could generate a "fireball" above these temperatures. Ether is particularly nasty in this regard. I have personally seen an ether flame appear to "jump" twelve feet. Any flame or spark is all that is necessary.
Corrected entry: During the evacuation scene when Robert's family is being scanned for virus by the soldiers, nobody cares about the dog. This was before the total extermination and they came to know that it's airborne just then. They didn't have any reason to believe that dogs would be immune to the virus. The dog must have been scanned/tested like anybody else. (Neville finds that dogs are immune to airborne infection only later).
Correction: But this wasn't day 1 of infection. There would have been evidence of canine infection prior to this day. So I would say YES, there was reason to believe that dogs were immune.
Corrected entry: In the ending scene after driving from New York to Virginia, Anna and the kid get out of a shiny SUV that looks like it just came out of a car wash.
Correction: Not a lot of traffic throwing up road debris on account of 99% of the world's drivers being dead. It's also very unlikely they took any unpaved roads to get there too. So, why would the car be dirty?
Corrected entry: Will Smiths Character is immune to the virus. As are those who have been refugee in the camp at the end of the movie. Will Smiths character has used approx. three years trying to find a cure/vaccine. But all that the woman is taking from N.Y to the refugee camp is the vial of blood, which contains the same immune blood that everyone else who survived has. Since the grenade exploded in the basement, she couldn't collect any usable data to provide the refugees with. Now, we can only assume that the refugees also have done some research with their own blood, and that the provided blood from Will Smiths Character wouldn't contribute in any way to their research.
Correction: First of all, he is not giving them a vial of his own blood. He is giving them a vial of blood from the infected woman - who had been injected with a (seemingly) successful cure. The vial therefore does contain antibodies, that can be extracted. Secondly, to say that they camp refugees would have done some research on their own is an assumption. There is no guarantee any of them is even a scientist, and if they were, there's no guarantee they were on Neville's level. He WAS one of the leading authorities on the virus, after all.
Corrected entry: Robert tells Anna that when the plague first began there were 6 billion people on earth. There were in fact an estimated 6.7 billion. While one could argue he was simply rounding down - this is unlikely because he has a very precise breakdown - 6 billion to start, 5.4 billion infected, 588 million killed, and 12 million healthy. Besides the missing 700 million people, how does he know that of the 12 million healthy the 3 of them are the only ones left alive? And how does he get these precise numbers?
Correction: He is upset, and yes he's estimating. The precise numbers about the infection come from the fact that he was directly involved in trying to stop it.
Corrected entry: Robert Neville is standing atop an airplane hitting golf balls. Sam sees a deer in the streets below. Neville picks up his gun and looks through the scope. When he does this the flashlight is on the right side of the gun. Later in the scene Neville and Sam follow the deer into the dark old bank, Neville enters with his gun raised, but the flashlight is now on the left side of the gun.
Correction: He might have two different guns. The gun probably is not one of a kind so it is possible that there are two of the same kind of guns with two different scope locations.
Corrected entry: In the scene where Robert is looking for his dog when she runs off into the building, as he looks round the corner at the mirror, you can briefly see the camera light.
Correction: No, it's just the flashlight on the end of Neville's gun, and you can see that it startles him.
Corrected entry: During Robert's first flashback, while arguing with his wife in the car, he hits a sick person, who leaves a blood smear on the passenger side window. During the second flashback of the same scene, when his wife gets out of the car, there is no blood on the window.
Correction: Flashbacks are things as he remembers them. Based on his current situation it is reasonable to say that he may not remember things the same way all of the time.
Corrected entry: When Will Smith is trying to hunt the deer and they go down the bridge, on the right side of the screen you can see someone's shadow running - a film crew member, probably. (He's the last man in Manhattan and the zombies aren't out yet, so who else could the shadow belong to?)
Correction: I watched this scene frame by frame and there is no shadow whatsoever.
Corrected entry: At the end he says that 1% of people are immune. That is 1% of 6 billion, and that is 60 million, not 12 million.
Correction: The actual line in the movie is "...LESS than 1% immunity", not exactly 1 percent. He's making a point of how small the level of immunity was, not making an accurate statistical analysis.
Corrected entry: When Robert Neville is playing golf, the camera is rotating around and you see him hit the ball. As he says "yeah," you can see two balls in a line. The camera then goes back down so you can see the dog's face and Robert swinging. You cannot see the balls as they are hidden, but Robert then hits the ball towards the hole. However having seen the shot beforehand, there were only two balls to hit and he couldn't have hit either cleanly like that as they where in a line.
Correction: You can see Robert use the club to move one of the balls into position to be hit.
Corrected entry: When Robert Neville sees Anna at his house after he wakes up, Anna was seen going to the cooker wearing a pink dressing gown with Ethan in a striped T-shirt. This changes with the next shot of Anna and Ethan who are wearing a grey top and a dark grey/black T-shirt respectively.
Correction: He does not really 'see' Anna and Ethan when he first gets to the kitchen, he is actually envisioning his wife and daughter. A moment later, reality sets in and then he truly sees Anna and Ethan, hence the change of clothing.
Corrected entry: The Ford SUV was destroyed when Robert goes out and attacks the Dark Seekers; I think it was even flipped as well. So how can the same truck be driven, by the woman and the kid that rescued him, at the end of the film?
Correction: They have a virtually unlimited supply of vehicles to choose from, including entire car lots full of similar model vehicles.
Corrected entry: If 12 million people survived, 6,488,000,000 would become "darkseekers" to be exact, or 5,988,000,000 to count from 6 billion - not 588,000,000 as Roberts suggests, unless the population prior to the outbreak dropped to 600,000,000. The numbers are out by an order of magnitude.
Correction: He's referring to-non mutant survivors. The virus (approximately) kills 90%, mutates 10% and has no effect on 0.2%.
Corrected entry: When New York is quarantined, all bridges were destroyed. However, Anna and Ethan drive to pick up Neville. Also in the alternate ending, the three characters drive over a bridge to leave the island.
Correction: Firstly, we never see how they arrive in Manhattan, they could have come by boat. Secondly, the alternate ending wasn't ever used as the official ending, so their exit via a still useable bridge cannot be considered a mistake.
Corrected entry: When Dr. Neville and Sam are trapped in the building after chasing a deer, when they are running out of the building and Neville jumps out of the window, two dark seekers jump with him, but when they land there's only one.
Correction: In the last shot of that scene, a wide angle of Smith looking down at the darkseekers, you can see (DVD version) two darkseekers. The second is harder to see, but it is obviously there in the lower left corner of the screen.
