Corrected entry: When the military attacks Ripper's base, Ripper and Mandrake are barricaded in Ripper's office. Ripper breaks out his window and starts firing at the advancing soldiers with what appears to be a Browning M2 .50 cal machine gun. That's all well and good, except notice how and where he supports the barrel with his hand. The Browning is air cooled. That wasn't a very smart place to hold it unless he was actually trying to burn his hand off.
Corrected entry: The tracks of the bombers on the "big board" descend on Russia from all angles. In reality bombers would only attack Russia from a few directions, as they must all start from a handful of air bases. For planes to take off from a mythical US base and then approach Russia from the Arctic or Europe would have required a flying time comparable to circling the Earth.
Corrected entry: When Group Captain Lionel Mandrake meets Lt. Colonel "Bat" Guano for the first time, it's very clear that neither man has ANY idea who the other is. In fact, with his hands up, Mandrake looks at Guano's name tag to ascertain whom he's communicating with. The problem is that Mandrake says something to the effect of "Colonel Bat Guano, if that really is your name!" Only his last name - "Guano" - appears on his name tag. There's also absolutely nothing that can be seen on the front of his uniform (which is the only thing Mandrake could have been looking at) that says "Bat." So how does Mandrake know that Lt. Colonel Guano's nickname is "Bat"?
Corrected entry: As the B-52 approaches the target and the bomb is dropped, the details of the ICBM base (silos, building, connecting roads, etc.) are visible. These details are then suddenly absent with the substitution of stock footage when the bomb explodes.
Corrected entry: When the B-52 was hit by the missile, it sustained a great deal of damage. However, the plane looks perfectly intact in all of the subsequent aerial shots (except for the black smoke).
Corrected entry: When, at the end, Dr. Strangelove is explaining his plan and his hand goes out of control, you can see the Russian diplomat behind him (on the left) trying desperately not to laugh.
Corrected entry: In the scene when Grp. Captain Mandrake confronts General Ripper in the latter's office with the knowledge that there is no Russian attack, he salutes and then turns to leave but finds both exits locked. He then returns to Ripper's desk and asks for the doorkey and the recall code for the planes that are en route to Russia. He hadn't asked for the code before trying to leave, yet he was prepared to leave without it. (00:21:00)
Corrected entry: It takes practically the whole movie for the lines on the 'Big Board' to approach their targets. When the planes are recalled, these lines beat a pretty hasty retreat.
