He's Just Not That Into You

The book was inspired by an episode of Sex and the City, "Pick-A-Little, Talk-A-Little", in which Miranda Hobbes asks Carrie Bradshaw's boyfriend, Jack Berger, to analyze the post-date behavior of a potential love interest. Because the man declined Miranda's invitation to come up to her apartment after the date, stating that he has an early meeting, Berger concludes, "He's just not that into you", adding, "When a guy's really into you, he's coming upstairs, meeting or no meeting." The book authors, Greg Behrendt and Liz Tuccillo, were writers on the show.

The book is a "self-help" guide aimed for single women. The premise of the book, as stated in the title, tells women readers that if a man in whom you are interested is not making the effort to pursue you, he is simply "just not that into you."

A film based on the book was released by New Line Cinema on February 6, 2009. Produced by Flower Films (Drew Barrymore's production company), filming was completed at the end of 2007. The film was released in theaters February 6, 2009.[1] Ken Kwapis directed the film, which featured an all-star cast including Ben Affleck, Jennifer Aniston, Drew Barrymore, Kevin Connolly, Jennifer Connelly, Bradley Cooper, Ginnifer Goodwin, Scarlett Johansson, and Justin Long.[2] Despite receiving mixed reviews from critics, it was a box office success, grossing over $180 million worldwide.

The book appears in Gilmore Girls episode "Pulp Friction", when Lorelai Gilmore prepares the Dragon Fly Inn's library for her interview and states that all of the good books are gone, leaving her with five copies of He's Just Not That Into You, which she hands an employee to dispose of. The book was also referenced in the movie Zombieland, in season two of Californication and in the series Vexed. VH1 discussed the book in their "I Love 2004" episode of their I Love the New Millennium special.
