With Vince Vaughn and Owen Wilson as a pair of brazen wedding crashers, this buddy/romantic comedy milks a few big laughs from its foolproof premise. Under the direction of David Dobkin (who previously worked with Wilson on Shanghai Knights), the movie ranges from bawdy romp to mushy romance, and that tonal identity crisis curtails the overall hilarity. But when the well-teamed co-stars are firing on all pistons with fast-paced dialogue and manic situations, belly laughs are delivered at a steady clip. Things get complicated when the guys infiltrate the family of the Treasury Secretary (Christopher Walken), resulting in a romantic pair-off between Vaughn and the congressman's oversexed daughter Gloria (Isla Fisher) while Wilson sincerely woos another daughter, Claire (Rachel McAdams), who's unhappily engaged to an Ivy League cheater (Bradley Cooper). Walken is more or less wasted in his role, but Jane Seymour and Henry Gibson make amusing appearances, and a surprise guest arrives late in the game for some over-the-top scene-stealing. It's all a bit uneven, but McAdams (considered by some to be "the next Julia Roberts") is a pure delight, and with enough laughs to make it easily recommended, Wedding Crashers will likely find its place on DVD shelves alongside other flawed but enjoyable comedies that embrace a naughtier, nastier brand of humour with no need for apologies. --Jeff Shannon
