Character mistake: The so-called cobalt chlorium (.) G, which is supposed to be used in the Russian doomsday device, has, according to the Russian ambassador (and Dr. Strangelove), a half-life period of 93 years. He then states that it would contaminate Earth for 93 years. However, per definition half of the radioactivity would still be left after this period. (00:47:30)
Dr. Strangelove (1964)
1 character mistake
Directed by: Stanley Kubrick
Starring: James Earl Jones, Peter Sellers, George C. Scott
Other mistake: When Col. Bat Guano shoots the Coke machine and it squirts him in the face, he's holding his head too high. You can see that he first gets the spray on the chin and then he ducks down to take it full in the face. (01:09:50)
President Merkin Muffley: Gentlemen, you can't fight in here! This is the War Room!
More trivia for Dr. Strangelove
Question: Was there any significance besides comedy to the very last scene of the movie where Dr. Strangelove stands and proclaims "Mein Fuhrer. I Can Walk." It was pretty funny as is, but I wondered if there was some sort of allusion or other intention to that line.
Answer: Peter Sellers improvised it. During that scene if you watch the actor playing the Russian character you can see him trying not to laugh at Seller's performance.
