Ben Stiller headlines an all-star cast in the hilarious domestic comedy of errors, David O. Russell’s Flirting with Disaster (A-). His adopted character’s cross-country search for his biological parents leads him hilariously into the arms of drug-dealers, FBI agents and a merry band of fellow travelers played by comic legends ranging from Lily Tomlin to George Segal and Mary Tyler Moore. Moore is outrageously tart playing against type. The story has a way of getting more and more perilous from what seemed like a pretty simple premise, and Russell’s dark searches within Pandora’s Box lead to some awfully funny findings about love and relationships in the modern age.
