"You have bewitched me, body and soul" is a famous love quote from "Pride and Prejudice." "You should be kissed, and often, and by someone who knows how" is a well known statement from "Gone With The Wind," and the quote, "You had me at hello" is from the film "Jerry Maguire."
"You have bewitched me, body and soul" is said by wealthy gentleman Mr. Darcy to the charming and intelligent Elizabeth Bennett in "Pride and Prejudice." The relationship between the two is spirited throughout the story. Near the beginning of the tale, Darcy will not dance with Elizabeth; at one point she vehemently spurns his feelings of affection, and the story ends with Elizabeth warmly agreeing to marry Darcy. His statement to her has an air of elegance to it, meant to be consistent with his societal status.
The quote about being kissed often from "Gone With The Wind" is said by roguish Confederate hero Rhett Butler to the ambitious Scarlett O'Hara, to whom he is attracted throughout the film. The backdrop of the connection between these two main characters is almost epic with its riveting aspects of the Civil War. It greatly enhances the sense of drama around the unpredictable relationship between Rhett and Scarlett.
In the case of the "Jerry Maguire" quote, a woman, Dorothy, says this to the love of her life, Jerry Maguire. These words mean that Dorothy fell in love with Jerry the first time he spoke to her.
