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 a short cartoon book of the same name by Michele Alexander and Jeannie Long.
Andie Anderson (Kate Hudson) is a writer who works for a magazine called Composure as the "How to..." girl. She is bored and wishes she could write more about important things, such as politics, economics, religion, poverty; stuff she actually cares about. She soon finds herself writing an article called "How to Lose a Guy in 10 Days". The idea comes about when Andie's friend, Michelle (Kathryn Hahn), experiences a minor breakdown after yet another break-up. Using her friend as inspiration, Andie reveals how she will actually start dating a guy and drive him away but "only using the classic mistakes women make".
