Trivia: Kubrick originally wanted to make this a serious drama. During the screenwriting process he was confronted again and again with situations that were completely truthful and serious, yet he was afraid and audience would laugh at how absurd it is. Such as general Turgeson referring to general Ripper's sending an entire bomb wing to obliterate Russia as "Overextending his authority". He eventually figured out that the only way to write it would be as a comedy.
Trivia: "Dr. Strangelove's" release in the United States was delayed due to the assassination of President Kennedy. The movie reflects this in an unusual and nearly undetectable dub job. After going over the contents of the survival kits on board the B-52, Major Kong is heard to say "A fella could have a pretty good weekend in Vegas with all that stuff." "Vegas" was dubbed in for "Dallas", which Major Kong actually says, after the assassination.
Trivia: The airport in the aerial photograph of "Burpleson Air Force Base" is none other than Heathrow.
Trivia: The ending was originally going to show a pie fight the War Room. Hence you see a long table that contains numerous pies. The scene was filmed but then cut from the final print. Stanley Kubrick decided not to let the black comedy devolve into a slapstick ending.
Trivia: Stanley Kubrick often used the combination of number '114' in his work. The name of the message decoder in this film is CRM-114.
Trivia: In later interviews, Stanley Kubrick revealed that George C. Scott did not want to portray General Buck Turgidson as a campy character in the film; he very much wanted to play Turgidson straight and serious (just as Kubrick had originally envisioned the entire film). Kubrick agreed and filmed Scott playing the role straight, but only on the condition that Scott rehearse the role as over-the-top camp. Scott agreed to camp it up in rehearsal only if the cameras weren't rolling, and Kubrick assured him they weren't rolling. However, Kubrick lied and filmed the campy rehearsals, as well, which were used in the finished film. As a result Scott refused to work with Kubrick again.
