Everyone has someone like Dupree in their lives - a friend who's a little too needy, a little too clingy, a bit of a social misfit who always says the wrong thing and doesn't know when to call it a night. But no one could possibly know someone who's as outlandish in his clueless cloddishness as Owen Wilson's titular third-wheel character because he's just too unrealistic, even for the sake of comedy. The guy could not exist - and if he did, his friends wouldn't keep him around as long as Matt Dillon and Kate Hudson do. Soon after serving as best man in their wedding, Dupree moves in with the newlyweds and proceeds to inadvertently wreck their house and their marriage. There are a couple of amusing lines and images here, but eventually the destruction becomes just too severe to bear. The role of Dupree is merely the same sort of unflappable slacker that has become the trademark of Wilson's career. But the typically radiant Hudson is squelched in a thankless part as the nagging wife. PG-13 for sexual content, brief nudity, crude humor, language and a drug reference. 108 minutes.
