By the 1970s, Ruggero was a director in his own right, directing comedies, crime films, musicals, and, most notoriously, horror films. His film Cannibal Holocaust included scenes of animal cruelty and torture, which lead to Ruggero’s arrest.

He was charged with obscenity and murder after articles surfaced claiming the film’s deaths were real. The charges were dropped when Ruggero’s supposedly dead actors defended him in court, but the film’s producers were charged with animal cruelty.
