The Italian comedian Toto managed to sustain his enormous popularity over three decades by both keeping up with the times and playing to his age. By 1962 rock ‘n’ roll had invaded Rome, and in this generation-gap comedy he’s a two-bit crook trying to keep his daughter at an expensive boarding school even as she’s busy getting into trouble herself. With sidekick Nino Taranto, Toto conspires to sell the landmark Trevi Fountain to an American tourist, among other laughable scams; zesty musical numbers and a puppy-love subplot serve as filler, and Camillo Mastrocinque, who directed some of Toto’s more socially conscious films, occasionally sneaks a mild attack on government corruption into this agreeable star vehicle. 107 min.
