"Vanity - It's my favorite sin" is a line used in which film?

The quote "Vanity - It's my favorite sin" is from the 1997 movie "The Devil's Advocate" where the character John Milton (played by Al Pacino), who is essentially Satan, says this line, signifying that he considers vanity to be one of the most appealing human sin. Vanity is shown to be a particularly potent as a sin; it is used/applied to easily and skillfully manipulate people. As the definition states and the movie shows, vanity is “Excessive pride or admiration of one's own appearance or achievements.”

In the film, Milton (Pacino) also says, "I rest my case. Vanity is definitely my favorite sin. Kevin (Keanu Reeves), it's so basic, self-love; the all-natural opiate. You know, it's not that you didn't care for Mary Ann (Charlize Theron), Kevin." Kevin had been easily coerced by a reporter and his own wife, Mary-Ann, into giving an interview. He was promised it would make him a 'star'.

"The Devil's Advocate" is an American supernatural horror film; it was directed by Taylor Hackford and written by Jonathan Lemkin and Tony Gilroy. Based on Andrew Neiderman's 1990 novel, it is about a gifted young Florida lawyer invited to work for a major New York City law firm. As his wife becomes haunted by frightening visions, the lawyer slowly realizes that the firm's owner John Milton is the Devil.
