Robert DeNiro and Billy Crystal team with Lisa Kudrow, Chaz Palminteri and director/co-writer Harold Ramis to make you a comedy offer you can't refuse in this laugh-out-loud mob hit. De Niro, deftly spoofing the wiseguy roles that have been a staple of his estimable career, plays powerful New York crime family racketeer Paul Vitti. Crystal, always one joke ahead of sleeping with the fishes, is shrink, Ben Sobel, who has just days to resolve Vitti's emotional crisis and turn into a happy, well-adjusted gangster. Yes, Sobel is a falmily pychiatrist.But surely this isn't the kind of family he had in mind.
