'The Great Beauty" recalls two other films set in Rome: "La Dolce Vita" and "Roman Holiday." The former takes huge bites out of the city's decadence and debauchery in much the same way as "The Great Beauty." The latter takes a mere lick at the pleasures proffered by Rome and declares satisfaction. The common thread here is that Rome is magical, addictive and life-altering. Had Princess Ann (Audrey Hepburn) stuck around for a few more days, the city would perhaps have robbed her of the will to go back.
