[1] Born in Viareggio, Piccioli graduated in arts, music and entertainment disciplines at the University of Bologna.
[2] After directing some shorts and some TV reports, he made his feature film debut in 1972, with Doppio a metà.
[2][3] After directing a giallo (The Flower with the Petals of Steel) and a prison-heist film (Puttana galera), starting from Sergio Citti's Beach House Piccioli devoted himself to production.
[2][3] As a producer, he was often interested in risky, unconventional ideas (such as Davide Ferrario's We All Fall Down) and in passion projects of established auteurs which had proved to be difficult to fund (such as Pupi Avati's Bix and Salvatore Samperi's Liquirizia).
[3] Piccioli is best known for having launched the film careers of Alessandro Benvenuti and Francesco Nuti, with whom he also founded the production company Union PN.
