Born in La Spezia into a family of Pisan origins, Biagetti studied medicine at the university of Pisa, and during this time he founded the stage company "The brigade of Doctors", for which he wrote several comic-grotesque plays.
 He moved to Rome in the early fifties, and there he had some experience as a documentarist and as an assistant director of notable directors including Joseph Losey, Giorgio Ferroni, Giacomo Gentilomo and Roberto Rossellini, who produced and wrote the feature film debut of Biagetti, the melodrama "Rivalità".
 After a badly distributed second work Biagetti abandoned films, devoting himself to the production and direction of commercials.
