The plot of Failure to Launch is utterly implausible, yet the movie is thoroughly fun. Tripp (laid-back Matthew McConaughey, Sahara, Dazed and Confused) is a 35-year-old man who still lives with his parents (Kathy Bates, Misery, and ex-quarterback Terry Bradshaw)--and they aren't happy about it. Eager to get him out of the nest, they hire Paula (Sex and the City's Sarah Jessica Parker), a professional motivator who feigns relationships with boy-men so that their improved self-esteem will lead them to leave the nest. But Tripp's not the usual insecure shut-in Paula's used to, and as sparks fly, Paula finds herself losing her professional distance. This sort of set-up drove classic screwball comedies of the 1930s and 40s; once you embrace the absurdity, the movie zips along with a surprising balance of humour and bittersweet shadings. Failure to Launch gets a huge boost from the supporting performance of Zooey Deschanel (Elf) as Paula's housemate Kit--part sourpuss, part tomboy, and entirely sexy and winning. McConaughey and Parker have enjoyable chemistry and carry the movie well, but Deschanel is an oddball romantic-heroine-in-waiting. Also featuring Bradley Cooper (Alias) and Justin Bartha (National Treasure).
