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: 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. (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: 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: 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: 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.
