This romantic comedy by John Hamburg (Safe Men) is hampered by the kind of overacting that the cast seems to enjoy more than the audience (Alec Baldwin’s unexpected turn as a Jewish blowhard is an exception until it loses force to choppy continuity). The hit-or-miss humor is pitched uncertainly between Woody Allen (Jennifer Aniston’s an Annie Hall figure to Ben Stiller’s cautious insurance executive) and the Farrelly brothers (more scatological jokes than you can shake a toilet plunger at); the worst fake accent in movie history (Hank Azaria as a French scuba instructor) and strident overreaching by Philip Seymour Hoffman both appear to be Hamburg’s fault. But it’s only 90 minutes long. PG-13.
