Corrected entry: When Mason and Goodspeed are locked in the cells together Goodspeed asks Mason what he did to pass the time when locked in the cells on Alcatraz. Mason mentions he dreamt of meeting his daughter one day. However it has previously been stated that Mason was in the rock 1962-63 but his daughter wasn't born until the 1970s.
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: 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. (00:15:30)
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 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: 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?
