Robert De Niro and Billy Crystal are back as the mob boss and his reluctant psychotherapist from Analyze This in the hilarious AnalyzeThat. Day after day, Paul Vitti (De Niro), New York's most notorious gangland figure, shuffles semi-catatonic around his prison cell,occasionally breaking into show tunes. Is Vitti having a nervous breakdown, or is his behavior a ploy for an early release? The FBI isn't sure ... and neither is his former psychotherapist, Ben Sobel (BillyCrystal). It will take time to examine the demons lurking in Vitti's mind--time that Sobel doesn't want to give. Not to Vitti. But the reluctant psychiatrist has no choice: Vitti is released to Sobel's custody, becoming his patient again and, even worse, his houseguest--bringing his demons and would-be hit men, both imagined and real.
