The Treasure of San Gennaro

Harry Guardino comes to Naples to steal the treasure of Saint Gennaro -- thirty billion, and even in lire, that's a lot of money. Relying on the advice of the city's godfather, Toto, he hires Nino Manfredi to be the straw boss of the Italian crew. However, when Manftedi discovers what they are stealing, he refuses as a true Neapolitan.... until Guardino's moll, Senta Berger, persuades him otherwise. He sees it as a means to help the poor of the city. This, however, being an Italian caper film, things go awry.

With Dino Risi directing from a script he co-wrote, they go awry in a very funny way. This is a frantic comedy that mocks everyone, from Guardino's genius who falls apart when anything goes wrong, the willingness of the sentimental gangsters to drop everything to attend a distant collateral relation's wedding. This is one you should not miss.
