There was a great skit on "Saturday Night Live" in the late 1970s that featured the late John Belushi as "The Thing That Wouldn't Leave." In it, Belushi played the friend of a young couple who, despite numerous hints, would not go home. Taking that idea and stretching it for almost two hours could have been a disaster, but the charm and talent of the cast of "You, Me and Dupree" make the ride worth taking.

Carl (Dillon) and Molly (Hudson) are about to be married in Hawaii. All of their friends have gathered except the best man, Randy Dupree (Wilson). When he finally shows up, having gone to the wrong island, no one is surprised. Dupree is Carl's best man, which he makes known by having a special insignia sewn onto his groomsman outfit. Dupree is fiercely loyal to Carl, so much so that he ends up fired for having taken the week off to attend the wedding without authorization. He's also lost his car and his apartment. Telling Molly that it will only be for a few days, Carl invites Dupree to stay with them. And, as the old time ads for comedies used to proclaim, hilarity ensues.

Credit the cast for making "You, Me and Dupree" a success. Wilson, with his crooked nose and patented "stoner-light" delivery, has a keen eye for what's funny. His take on Dupree could have been very over the top, making the audience see him as a pest. But instead he gives Dupree an almost childlike sweetness. Whether he upgrades the newlyweds cable service without their knowledge or walks out of a job interview when he discovers that "V-J Day" isn't recognized as a holiday, Wilson puts the audience on his side. Dillon does a fine job as a man who slowly realizes that, whether at home or at the office, his life is not his own. Beautiful and talented like her mother, Goldie Hawn, Hudson makes a perfect third side in this casting triangle. The supporting cast deserves just as much praise. In a supporting role Michael Douglas gets the rare chance to show his comedic side while Seth Rogen, so funny in "The 40-Year Old Virgin," gets laughs as a husband who doesn't realize he's henpecked.

Like last week's "The Devil Wears Prada," this is a film that will entertain without dumbing itself down for the audience. On a scale of zero to four stars, I give "You, Me and Dupree"
