22/25. Major Kong's comment about the survival kit in Dr. Strangelove was originally "A fella could have a pretty good weekend in Dallas with all that stuff". "Dallas" was overdubbed with "Vegas" after President John F. Kennedy was assassinated in Dallas. Kong still mouths the word "Dallas".
23/25. Stanley Kubrick shot most of Peter Sellers' scenes in Lolita with two or three cameras at once. The actor did his most inspired work on the first take, so Kubrick used that technique to get all the angles he needed without losing spontaneity.
24/25. George C. Scott was reputedly annoyed that Stanley Kubrick was pushing him to overact for his role in Dr. Strangelove. While he vowed never to work with Kubrick again, Scott eventually saw this as one of his favorite performances. Many fans consider it some of his best work on-screen.
25/25. Alex performing "Singing in the Rain" as he attacks the writer and his wife was not scripted. Stanley Kubrick spent four days experimenting with this scene, finding it too conventional. Eventually he approached Malcolm McDowell and asked him if he could dance. They tried the scene again, this time with McDowell dancing and singing the only song he could remember. Kubrick was so amused that he swiftly bought the rights to "Singing in the Rain" for $10,000.
