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. He came back to cinema in 1968, directing two commercially successful films which had some
political and
social commitment, then since 1972 he focused on more low-profile genre films, in which he was sometimes credited as
Pier Giorgio Ferretti. == Filmography ==
