In the scene on the train in "The Manchurian Candidate," Janet Leigh watches as a trembling and overwrought Frank Sinatra is such a mess that he can't even light his own cigarette and actually drops it in his drink. Then he storms out of his seat and she follows him and they engage in banter that he can barely keep up with while he stands there sweating profusely.
She finds him irresistible. She gives him her phone number - which despite the fact that he's a wreck, he doesn't write down but manages to remember days later.
Back home in NYC, Sinatra gets in a really brutal fight with a "Houseboy" he somehow remembers, in the back of his mind, is actually a North Korean who was present at his brainwashing. The two of them trash an apartment and Sinatra is taken to the police station. He calls Janet Leigh... who is now so thrilled that she calls up her fiance and breaks off their engagement so she can devote herself to the quivering mass that is Sinatra.
This kind of thing NEVER happens to me in real life.
