The Peacemaker (1997)

Factual error: The Russians stopped using steam locomotives in the 1970's. So bringing one out of retirement in 1997 to haul nuclear warheads would mean that your highly secret nuclear train would be well known among rail enthusiasts for weeks before.

Factual error: When LtCol Devoe enlists the help of the US Air Force in Turkey to intercept the truck carrying the nuclear warheads, the squadron is operating Eurocopter AS 565 Panther multirole helicopters. The USAF does not and has never had AS 565's in their inventory.

Plot hole: When the diesel train stops in the tunnel, one of the soldiers tells another one how far they are from the spot where the nuclear detonation will take place. Do the math: the distances don't work out. At least one of the trains would have to do over 100mph AVERAGE to put enough distance between them. Military precision, indeed.

Thomas Devoe: I don't know about these guys, but General Aleksandr Kodoroff doesn't ride around on a nuclear transportation train. It's like Ivana Trump on the subway.

Hamilton: Russia, what a fucking mess! God, I miss the cold war.

Julia: Where the hell is my military liason?
Devoe: Colonel Thomas Devoe reporting as ordered, ma'am. I'm sorry about in there, sometimes my enthusiasm gets the better of me.
Julia: No problem. Would you like some coffee?
Devoe: I'd love some.
Julia: It's over there.

Question: At the end of the movie, George Clooney and Nicole Kidman are trying to remove one of the small explosive plates that surround the plutonium sphere in a nuclear weapon. Couldn't they have just disconnected the wire connected to the explosive plate to prevent that trigger charge detonating properly? Or would it have detonated because it was touching the other plates?

Question: Wouldn't they know something was up when the train explosion wasn't as huge as it should have been (because many of the bombs were missing, and thus making the explosion smaller)?

Question: As Gavrich fled into a building being chased by Devoe and Kelly the helicopter operators informed that the (radiation) signal just disappeared. Would it really disappear so quickly?
