A man trying to save his relationship with the woman he loves finds himself sinking into a quicksand of small lies and half-truths in this comedy. Paul (Jason Lee) is a regular guy who is engaged to marry Karen (Selma Blair); while Paul loves Karen, he’s more than a bit nervous around her family, even though her father (James Brolin) has already given him a job in the family business. Shortly before the wedding, Paul's friends throw him a bachelor party, complete with a boatload of liquor and a squadron of grass-skirt-clad tiki dancers. Paul strikes up a conversation with one of the dancers, the cheerful if inept Becky (Julia Stiles), and the next morning, he wakes up bleary-eyed with a massive hangover — and Becky in bed next to him. Paul soon receives a phone call from Karen saying she's stopping by for a visit, and Paul scrambles to get Becky out of his apartment. Paul attempts to explain some incriminating evidence with a few white lies, but a messy situation gets messier when Paul runs into Becky at a pre-wedding family get-together...and discovers she's Karen's cousin. A Guy Thing also features Shawn Hatosy, Lochlyn Munro, and Julie Hagerty. ~ Mark Deming, Rovi LESS
