How to Lose a Guy in 10 Days is a 2003 romantic comedy film directed by Donald Petrie, starring Kate Hudson and Matthew McConaughey. It is based on the picture book of the same name by Michele Alexander and Jeannie Long. The book has no narrative, only a list of comedic dating "don'ts", so the characters and plot were created for the film. In the film, advertising executive Benjamin Barry makes a bet that he can make any woman fall in love with him, while women's magazine writer Andie Anderson plans to write an article about how she led a man to dump her, putting them at cross-purposes after they choose each other as their quarries. Andie employs a number of the dating "don'ts" from the picture book in her efforts to get Ben to break up with her.
