Corrected entry: When Hancock is in the hospital after the liquor-store robbery a reporter mentions that he was hospitalized due to "multiple gunshot wounds". During the robbery, however, he was only shot once.
Corrected entry: When Hancock gets inside the house you can see set lights on his sunglasses.
Correction: Since it's inside the house, there's a chance the reflection could be from lamps or other light fixtures in the house. If you could see the whole lighting stand onscreen, that would be one thing, but reflections of a light could be just light fixtures.
Corrected entry: When Hancock tells Michel to call him an asshole one more time and throws him into the air, notice that when the boy Hancock called "Goggles" looks up in the air he wears glasses but they suddenly disappear. (00:21:15)
Correction: In between the two shots, "Thickness" manages to change his shirt, hair color, and body build. "Goggles" manages to change his shirt, glasses, and ethnicity. So obviously, they are not the same children in both shots.
Corrected entry: (SPOILER ALERT) When Hancock returns in the morning after he has been tossed out of the house by Mary, he tries to stab her with a fork only to see it bend when she is stabbed. But later you find out that when these two are close to each other, their powers weaken and they can be killed and shot, just like normal people.
Corrected entry: Hancock stops the train ramming John's car, but he's a superhero with super-strength and the ability to fly. Why not just lift the car off the tracks and out of danger?
Corrected entry: John Hancock and Mary Embrey are both endowed with super powers, such as flight, healing ability, and invulnerability. The latter is demonstrated in that Hancock was unable to receive an IV when he was checked into the hospital (in the 1930s) as the needle simply broke off. How then is Mary able to have pierced ears? A needle would have broken, and even then, the wound would heal rapidly.
Correction: She could have had that done when they were together and vulnerable. Keep the earrings in and it couldn't heal over, so would presumably just heal around the hole.
Corrected entry: At the start when Hancock is stopping the car on the bridge, he rams his feet through the car floor to stop it. As the wide shot begins to show the car stopping, the back wheels of the car have locked up as though the handbrake has been applied, if Hancock was stopping the car this way there would be no wheel lock-up as the car is being stopped this way. (00:05:00)
Correction: He just shoved his feet through the bottom of the car. Damage to the rear axle is a given and would certainly freeze up the wheels.
Corrected entry: In the scene where Mary Embrey goes to Hancock's trailer to tell him about their past, Hancock says something to the effect of "sisters don't kiss their brothers the way you kissed me in the kitchen last night." In fact, the night before, they never kiss, they just come real close to kissing before she throws him through the wall.
Corrected entry: The locomotive in the train wreck was a low-powered switching engine. Dozens and dozens of rail cars kept piling up, yet that engine would not have been powerful enough to pull such a long train in the first place.
Correction: It is very possible that there were multiple engines pulling the train, it actually is quite common to have more than one.
Corrected entry: Spoiler Alert: When the 'superwoman' tells Hancock that they were built in pairs so that they could live together and die together, it completely contradicts what happens at the end of the film. As she is is lying dead on the hospital bed, Hancock uses the last of his strength to move far away from her, thus causing her to live again and both of them start becoming immortal once more. If this is the case, then when one of their kind dies, as long as the one who is alive is far enough, the being that died will come back to life and both will become immortal again.
Correction: She explains to him that there is a reason why they lose their powers over time when they pair up, and that is so that they can grow old and die together like normal mortals. SO, presumably the others died because they chose to become mortals and live normal human lifetimes.
Corrected entry: After Hancock gets called out of jail, the officer tells him to rescue the cop that's down. The criminals pull out the rocket launcher and it pans over to a view of the officer when she is near the tire of the police car. But when Hancock gets to her, she's moved to the middle of the car somehow.
Corrected entry: In the beginning of the movie when Hancock stops the robbers and impales the SUV on the building, the engine should come out from the hood. Instead spires penetrate the engine block.
Correction: The engine "should"? One engine mount can have broken, tilting the motor over in its compartment, allowing the spire to pass through without the engine protruding.
Corrected entry: Hancock meets up with the super powered woman, who explains to him that he will start losing his powers the longer he's near by. Problem is, when he gets shot in the liquor store, he's nowhere near her. Even if he had just come directly from their home it wouldn't matter, because later in the movie it's established that Hancock regains his powers when he's only a few feet away from her in a very short time. (When he's leaps out the window, she miraculously awakens.) And he'd only been out of her sight for a few moments before he's up and flying again.
Correction: She told Hancock in the hospital that the "power lost" has never been this fast before, so either the writers caught the goof in time or it really is planned.
Corrected entry: After Hancock is shot and taken to the hospital, the press and police are swarming the place, trying to get a statement from the husband as he enters. With people everywhere and all eyes on Hancock, how did a group of heavily armed men all dressed in black casually walk in and start attacking? We're led to assume they snuck in, since no weapons are shown when we see the henchmen in the hallway, and the leader (Red) rides up the same elevator with the husband and son.
Correction: They were dressed in official looking clothes and were able to pass as members of the SWAT team.
Corrected entry: If Hancock and Mary are connected (as established out of nowhere through the lengthy fight scene towards the end of the movie in the hospital, where Hancock takes the blows, and the damage appears on Mary's body), how does Mary flatline, and Hancock get up and leave in order to save her? Not to mention that, considering the focus they made on the 'connection' since Mary was on the threshold of death, a leap out a window should have left Hancock splattered all over the ground.
Correction: It requires a suspension of disbelief, but Hancock pulls together his last bit of strength to get out of the hospital. Sort of like Superman lifting a continent of Kryptonite in "Superman Returns"; super heroes are constantly called upon to use their last bit of reserve energy when the chips are down.
Corrected entry: In scene where Hancock speaks to super woman in the kitchen after the bank robbery part, she spots a bruise on Hancock's hand, when the only chance he had to get bruised was in the bank, which was far away from her.
Correction: Plenty of time between the robbery and him showing up at the house with a bruise.
Corrected entry: There's inconsistency in Hancock's strength. When he stops the car in the beginning of the movie, he needs a few meters. When he stops the train, he doesn't move even one inch.
Correction: He's just as strong in both events. In the car his body is in motion with the SUV; he digs his heels into the pavement and pulls the car to a stop. On the tracks he braces himself against the pavement from a standing position and gets hit by the train. Obviously something to do with his powers. Whenever he's in motion (like all his first attempts at landing) he tears up pavement when trying to stop; when bracing himself standing still he becomes an immovable object.
Corrected entry: Throughout the film stationary, unoccupied cars are hit with debris, other cars, fridges, superheroes, and are turned upside down, knocked around or thrown sideways. Not one single car alarm goes off.
Correction: Not a lot of people bother with car alarms anymore because no one pays them any attention. They're just nuisances as far as most folks are concerned. Many cars still come with an alarm that goes off if someone tries to manually unlock a car that has been locked by remote, but that would not be activated by debris impacting the vehicle. There is too much speculation for this to qualify as a legitimate mistake.
Corrected entry: In the box Hancock has from attack in the 1930s, it shows the back of a one dollar bill. During the attack he is going to see Frankenstein (a new movie at the time) which was released in 1931. The current back of the one dollar bill was not released until 1935.
Correction: Just because a movie was released in a specific year doesn't mean it wasn't still in the theater a few years later! Back then, movies didn't come out by the dozens every month, so they were available for much longer. For example, Gone with the Wind came out in 1939, and my mother saw it in the theater in the 70's. And Rocky Horror has been in the theaters continuously since its release in 1975. We don't know if this was a new release, or just new to him.
Corrected entry: When Embrey is talking with Hancock in jail via the telephone intercom, they're facing each other through wire mesh reinforced glass. Hancock uses his fingernail to score a circle in the glass and then taps it out as a perfect circle. This type of glass would not tap out with scoring, since there's a wire mesh bonded between two layers of glass. At most he would've dislodged the interior pane and shattered the exterior pane.
Correction: Hancock has nails that with the lightest pressure have cut through the glass - I'm sure with this and his strength cutting through the metal wire beneath at the same time would be no problem.
Correction: There were in fact two gun shots which can be heard in the scene where Hancock throws the bar at the robber, and when it cuts to Hancock's torso you can see two bullet wounds, he even touches both.
