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: 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: 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: 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. (01:45:05)
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.
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 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.
