Carl and Molly Peterson (Matt Dillon and Kate Hudson) are just starting their new life together. There's just one unfortunate hitch in their perfectly constructed new world...And his name's Dupree. Randy Dupree (Owen Wilson), Carl's oldest friend, has found himself with nowhere to go after being fired. Carl yanks pal out of the bar he's living in and invites him to temporarily crash on the couch. That's where things spiral completely out of control for the happy new couple.
I was pretty disappointed with this movie. They really tried to cash in on Owen Wilson's popularity from Wedding Crashers (a much much funnier movie!), but this movie was nowhere near as funny. Matt Dillon was pretty bland and basically every funny scene in the movie was in the commercial.
I would half-heartedly recommend this movie on video. You'd be much better off just waiting for it to show up on cable and check it out then.
