Corrected entry: The helicopter used to drop the US Navy Seals in the water is a CH-3, this US Air Force helicopter retired a few years before. More realistic would have been a US Navy CH-53E.
Corrected entry: At the start of the movie where Goodspeed is collected by Womack, he states that VX gas was "invented accidentally". Later on, in the war room, one of the army experts around the table describes VX as "specifically designed to withstand napalm". So, designed, or accidental?
Corrected entry: As Mason is interrogated, he breaks the window. Prior to that he takes a coin and draws a circle on the window. The purpose of that must be that when he uses force the window will break where he has made the circle. That does not happen. The window breaks in the center of the circle, not at the rim as intended.
Corrected entry: In the beginning when Hummel is talking to his wife's gravestone, the emblem on his hat is broken.
Corrected entry: Alcatraz does not have narrated tours by guides. They use a self guided tour where you get a walk-man and listen to a tape.
Corrected entry: When General Hummel calls the FBI director. The director only asks: "Who is this?" and "I wanna know who this is." He says nothing else, but when he hangs up the phone, his secretary says that she'd cancel his reservations. Most surely she wasn't eavesdropping on another line nor could she have overheard the conversation from where she was standing as the phone call wasn't on loudspeaker, otherwise the director wouldn't have had the receiver to his ear.
Corrected entry: In one scene of the shower-room shootout you can see a SEAL land on the floor with close-up of his face. On the floor next to him there is a spent 9mm round. If you take a closer look, you can clearly see that it is a blank for use in movies. The "bullet" is still there, but on a real 9mm round the bullet will be missing when the spent cartridge is ejected from the gun.
Corrected entry: When the Thermite Plasma bomb is dropped accidentally and Nicholas Cage is flying through the air because of the detonation, you can see that he (the stuntman) is hung up on the hips. Maybe you can only see this one in the DVD version, frame by frame.
Corrected entry: In the scene where Nicholas Cage is supposedly making love to his girlfriend on the rooftop, Cage gets a phone call and has to leave. When his girlfriend gets up you can see her underwear.
Corrected entry: Alcatraz has been de-commissioned for many, many years when this movie takes place. Why then are there still active flamethrowers with the randomly rotating gears? Why were they there in the first place? It couldn't have been to prevent inmates from escaping. The whole flamethrower part is completely absurd.
Corrected entry: Having removed the nerve gas from the final rocket, and then discharged said rocket in order to take out the marine who is trying to kill him, why does Goodspeed still need to retrieve the guidance chip from the gas canister? The purpose of the chip is to guide the rocket, and as there is no longer a rocket to guide.
Corrected entry: When Stanley is doing the 360 in the Ferrari, the airbag deploys and Stanley puts the gun against the bag so he's not crushed like a grape. About 4 seconds pass and he never pulls the trigger, so the airbag was not popped.
Corrected entry: Ranger Bob said that he spent a couple years in Alcatraz. If the prison is closed since 1963, he must have been a baby when he was arrested.
Corrected entry: It is repeated several times throughout the movie that if you come into contact with the chemicals, inject the atropine into your heart. In real life, that would kill you. If you are exposed to a chem agent, you would place an injector about the size of a paint marker against your thigh and press a button on the back of it, which would extend the needle and inject the atropine. If you injected yourself without having been exposed, as Goodspeed was instructed to do in the bomb room in the beginning of the movie, that would kill you too.
Corrected entry: At the end of the movie, Mason tells Goodspeed, "It's been a long time since I've said thank you to anybody, but, thank you." However, he said thank you to Goodspeed earlier in the movie, after Goodspeed told Mason's daughter that he was helping the FBI.
Corrected entry: In the scene where all of the men are being taken by helicopter to Alcatraz, a soldier hands Goodspeed a syringe and says something along the lines of 'if you come in contact with the chemical, inject this into your heart.' If Mason was sitting with the men on the helicopter, why was he so surprised when Goodspeed stops him in the tunnel and tells him that the terrorists have chemical weapons. Was he not paying attention on the helicopter?
Corrected entry: Near the beginning Goodspeed tells his girlfriend to come to San Francisco but changes his mind once he finds out what's really going on. Instead of having the FBI simply pick her up. Why not send her back home on the next flight out? He works for the Feds, how hard could that have been to arrange?
Corrected entry: Data on John Mason in FBI database doesn't show his name when Stanley Goodspeed's colleague searches in it [just a string of X's], in order to hide his identity [as remarked by FBI director Womack]. However, there is a full name and address of nearest relative [his daughter Jade]which is would make him easy to identify in any case.
Corrected entry: When the General is killed, there is a shot of him flying back. During this shot, there are drops of blood visible on the camera lens.
Corrected entry: In the boiler room where Mason goes under the flames. How is it possible that these flames still work after all these years that alcatraz has been closed?
Corrected entry: In the scene where Goodspeed is riding a kid's motorcycle he just stole, he calls an FBI man to get Mason's daughter's address. After getting the address, we see him pull up in front of the daughter's house. This scene takes place in San Francisco. If Goodspeed lives and works in the Washington D.C. area, how does he find his way to the house so quickly and without getting lost?
Corrected entry: During the chase scene, Mason is called by the car's angry owner saying "You stole my Hummer". Mason replies : "I'm only borrowing your *Humvee*". How did Mason know what the abbreviation of "Hummer" was if he was so out of touch with present day ?
Corrected entry: When the Marines are making their way to Alcatraz in their minisub for a brief moment you are shown a computer screen on the sub. It shows really cool 3D animation. In the next shot you can see all the screens on the sub, but there's only radar-like screens. The 3D animation is gone.
Corrected entry: In the end, when the F/A-18s are heading for Alcatraz, the lead pilot says their speed is 450 knots, then as they are getting closer, he says increasing speed to 500 knots. If they are in such a hurry, why aren't they going as fast as possible? The F/A-18 has a top speed of approx mach 1.7, so 450/500 knots is nothing.
Corrected entry: Everyone in the Seal team is wearing dark clothing in order to be "invisible", and therefore they have also painted their faces in camouflage colours, all but Goodspeed and Mason. They are happily sitting there with their white uncamouflaged faces. What's the point of the rest being camouflaged then?
Corrected entry: In the scene right after Nic Cage's Ferarri is destroyed, the guy on the dirt bike is talking to him. If you listen closely you can tell the bike isn't on or else you would hear the engine idling which is quite obvious on a dirt bike.
Corrected entry: When the two Marine captains first report to General Hummel on Alcatraz, they salute him, and he returns their salute. One of the captains and the general are uncovered (that is, they aren't wearing hats, or "covers"), and the other captain is wearing a black beret. All are outdoors. When in full uniform, Marines 1) never go outdoors uncovered, 2) never salute uncovered, and 3) do not wear berets of any sort. The Army does all of these, but the Marine Corps never has.
Corrected entry: Why does Goodspeed ask for a gun at the Fairmont Hotel? At that time he couldn't be aware that he was going to join the SEALs later in the movie...?
Corrected entry: After the first rocket is launched, Cpt. Frye says 'let's be all we can be'. That was the Army slogan. No Marine would say that.
Corrected entry: When director Womack is explaining that Mason is in prison for stealing microfilm with top-secret files on it, and again at the end of the film when Goodspeed is looking at the microfilm, it is mentioned that the John F Kennedy assasination files are on the microfilm. Alcatraz closed in April of 1963 and JFK was not assasinated until November of 1963, so this information could not possibly have been on the microfilm.
Corrected entry: In the shower room scene when Hummel is about to close the eyelids of one the dead FBI team. The dead man's eyelid twitches just before Hummel touches it. That's strange as the man is meant to be dead.
Corrected entry: When the group first enters Alcatraz, Sean Connery says that he memorised the pattern of fire flashes so he could roll under the boiler, but when he gets to the other side, he simply opens the door to the outside. When he originally escaped from Alcatraz, why didn't he use the door instead of trying to roll under the boiler?
Corrected entry: In the meeting when Hummel speaks with the FBI, Whitehouse staff, etc, the time is said to be 11:58pm. Hummel then says "You have 40 hours until noon, day after tomorrow." That would only be 36 hours.
