A Guy Thing
A Guy Thing is a 2003 American comedy film directed by Chris Koch and starring Jason Lee, Julia Stiles and Selma Blair. Plot
Paul Morse (Lee) and Karen Cooper (Blair) are about to get married in Seattle. During his bachelor party, Paul has a chat with one of the dancers at the party, Becky Jackson (Stiles), and they find that they have an affinity for each other. Paul wakes up the next morning and is terrified to see Becky in the bed next to him. Assuming they slept together, Paul rushes Becky out of his apartment and hopes never to see her again. He tries to cover up the connection for the few days before the wedding. Unfortunately, Becky unexpectedly shows up around town and turns out to be Karen's cousin. Even worse, Becky's malicious ex-boyfriend cop Ray Donovan (Munro) had Becky followed and photographed. Becky and Paul meet again to steal those pictures from Ray's apartment. Further problems arise with family and friends consistently showing up at the wrong times. Crabs, dirty underwear in the toilet tank, a horny best friend, and a best man/brother who is in love with the bride all provide for a week of wedding preparation hijinks. Through the snowballing of all his implausible lies and half-truths, Paul receives corroboration and support from an unexpected corner; what seems to be a coordinated network of other men, including friends, complete strangers and, to Paul's astonishment, Karen's own father; all who give the same explanation: "It's a guy thing".
