The footage he gathered there formed the structure of his first film effort, La sporca guerra (The Bloody War), intended as a non-aligned political documentary.

His feature debut, Lontano dagli occhi (Out of Sight), the story of an Italian reporter's coverage of a trial in Frankfurt of former Nazi officers for crimes against humanity, was never completed and remains unseen.

One drifts into acting in pornographic films while the other loses his ability to distinguish reality from fantasy and succumbs to violent impulses.

Hot on the heels of that picture, Cavallone began directing a musical-comedy that he was forced to abandon in mid-production due to budgetary constraints.

In 1971, Cavallone directed Quickly, spari e baci a colazione, a low-budget affair that utilized discarded sets from bigger pictures and incorporated footage from the uncompleted musical.

In 1980, Cavallone directed the surrealist erotic-mystery Blow Job – Soffio erotico and later that year La gemella erotica – Due gocce d’acqua, a project along similar lines.

In 1983, he contributed the story to Umberto Lenzi's fantasy film Ironmaster (aka La guerra di ferro).
