Danny DeVito's Hoffa is designed as an epic worthy of Orson Welles, a multigenerational tale of a powerful, little-understood man who rose from nothing and destroyed himself by subsuming his humanity. Interestingly, the seeds of this Citizen Kane-like ambition can be traced to some of DeVito's earliest directorial efforts, three episodes of Taxi: ''Jim's Mario's,'' about spaced-out heir Jim buying the cabbies' hangout; ''Sugar Ray Nardo,'' about Tony's teaching Elaine's son how to box; and ''Elaine and the Monk,'' about a doomed, week-long love affair.
