The setup is promising: The Romano mob family know that they're being betrayed by a hidden FBI informant in their ranks, so they decide to send a family member under cover to destroy the evidence against them--but the only family member the FBI won't recognize is the family black sheep, Corky (Chris Kattan), a touchy-feely aspiring veterinarian. But once Corky goes undercover, his klutzy ways accidentally make him the star of the FBI, sparking envy from his fellow agents and arousing suspicion in the mob. Though the script of Corky Romano declines as the movie goes on, Kattan actually keeps the picture going; his spastic, sniveling, childish energy is engaging, and at its best the production bubbles over with silliness. It only falls flat when Kattan has to behave in a remotely adult manner, which fortunately doesn't happen very often. Cheerful dopiness. Featuring Peter Falk, Peter Berg, and Chris Penn as mobsters. --Bret Fetzer
