During 1963, working together with Carmelo Bene having just arrived in Rome and Pepe Lenti, a film taken with two cameras, one in each hand, on "Cristo '63" a theatrical work censored by the police. It was either hidden or destroyed, consequently nobody was ever able to see it.

Among much material filmed but never assembled, these films may be remembered. Some were terminated and others have been considered as "work in progress" over a period of many years.

In 1964 with Gianfranco Baruchello, "Verifica Incerta" was a cinematographic massacre of the famous Hollywood films bringing to mind Dada. It was presented for the first time in Paris, causing the enthusiasm of Marcel Duchamp, Man Ray and Max Ernst and the evident scorn of many famous Italian cinematographic critics. John Cage was enthusiastic about the sound track; he presented it to the New York Museum of Modern Art. This method of assembly, this "detournement" was copied by "Blob" many years later.

In 1965, the "In viaggio con Patrizia" covers a car journey written in the style of the phonetic poetry of Patrizia Vicinelli. The music was directed by Paolo Fresu.

In 1966 with Perla Peragallo and Leo De Berardinis he put on stage pieces from Amleto to be used for playing in the theatre. Other documents were filmed in Marigliano.

In 1967 "No stop grammatica" was an event lasting 12 hours at the Feltrinelli bookshop in Rome. The sound track (produced for the background) was put together by the crowd, re-composed without listening to them, by pieces of magnetic film that had been distributed in various locations. Almost all the film directors and actors belonging to the Roman avant-garde were there.

Later, shorts where special effects were used attempting to create a new visual language, able to describe the "new geography of perception and infiniteimages, arising from the long ago phylogenic past of our animal ancestors" a gift from psychotropic substances. "Transfert per camera verso Virulentia" on the work for the theatre by Aldo Braibanti (1967), "Orgonauti, evviva!" and "Il grande freddo" (1970). This work was in opposition to the aesthetics of box-office films which were starting to sell off the stereotypes of hippie adventures using special effects "to flavour the tasteless swill of a cinema that never changed in its essence".

He was condemned at the same time as Braibanti to two years of prison ('68/'69) where he sent out letters secretly from the Regina Coeli prison that were read at the same time as films found in the discarded moviola boxes were being shown. In "L'occhio è per così dire l'evoluzione biologica di una lagrima" together with documentaries filmed by Grifi at Auschwitz, Monica Vitti can be seen trying to cry, a piece from "Deserto rosso" by Michelangelo Antonioni, while the speaker (Carlo Silvestro) reads a document on the violent assaults undergone in 1969 by a group of prisoners during a prison transfer and in the Mamone prison in Sardinia.
