“I should stop ruining my life searching for answers I'm never gonna get, and just enjoy it while it lasts.”

Woody Allen

Hannah and Her Sisters (1986).

“You know, the whole American culture is going down the drain, you can't turn on a television set and see anything, or walk in the street and not find garbage, or neighborhoods that were formerly beautiful now have McDonald's in them, and it's all a part of an enormous degeneration of culture in the United States. People that exist in that culture are forced to make moral decisions all the time about their lives, their occupations, their love-lives, and they make decisions that are commensurate with what's happening to them in this culture, and it's too bad that that's happening because that's what Manhattan is about, that New York used to be such a great city, so wonderful, and it has to fight every day for its survival against the encroachment of all this terrible ugliness that is gradually overcoming all the big cities in America.
This ugliness comes from a culture that has no spiritual center, a culture that has money and education, but no sense of being at peace with the world, no sense of purpose in life. They don't know what they're doing, or why they're here. They have no religious center, they have no philosophical center, and so they act, they do what's expedient at the moment. They have no long view of society. They only have the view of quick money, and kill the pain of the moment, and so instead of dealing with the real problems that exist, that are complicated, they sweep them under the rug by turning on the television set, or taking cocaine, or doing many things that enable them to escape confrontation with the unpleasant realities of the world.”

Manhattan Murder Mystery (1993)

“The film studios learned to our dismay but to their pleasure that if they spent $200 million making a film they could make half a billion on it. So they were not interested anymore in quality films… They can’t afford to be that risky at those prices. Consequently you’re getting a lot of remakes, sequels, dopey comedies full of toilet jokes…”

“She quarreled with the nanny and accused her of brushing Misha's teeth sideways rather than up and down.”

Woody Allen book Mere Anarchy

Mere Anarchy (2007)

“To love is to suffer. To avoid suffering, one must not love. But, then one suffers from not loving. Therefore, to love is to suffer, not to love is to suffer, to suffer is to suffer. To be happy is to love, to be happy, then, is to suffer, but suffering makes one unhappy, therefore, to be unhappy one must love, or love to suffer, or suffer from too much happiness — I hope you're getting this down.”

Woody Allen

Love and Death (1975)

“When it comes to sex there are certain things that should always be left unknown, and with my luck, they probably will be.”

Woody Allen

Everything You Always Wanted to Know About Sex* (*But Were Afraid to Ask) (1972)

“Allen: That's quite a lovely Jackson Pollock, isn't it?
Woman: Yes, it is.
Allen: What does it say to you?
Woman: It restates the negativeness of the universe. The hideous lonely emptiness of existence. Nothingness. The predicament of man forced to live in a barren, godless eternity like a tiny flame flickering in an immense void with nothing but waste, horror, and degradation, forming a useless, bleak straitjacket in a black, absurd cosmos.
Allen: What are you doing Saturday night?
Woman: Committing suicide.
Allen: What about Friday night?”

Woody Allen

Play It Again, Sam (1972).

“Harry: Between the Pope and air conditioning, I'd choose air conditioning.”
