Luca Barbareschi (July 28, 1956, Montevideo) is a Jewish Italian-Uruguayan actor, television presenter, and former member of the Italian Chamber of Deputies.
He was one of four actors whom the Italian police believed had been murdered in the making of the 1980 horror film Cannibal Holocaust, where he also abused and killed a young piglet. So realistic was the film that shortly after it was released, its director, Ruggero Deodato was arrested on suspicions of murder. The actors had signed contracts to stay out of the media for a year in order to fuel rumours that the film was a snuff movie. The court was only convinced that they were alive when the contracts were canceled, and the actors appeared on a television show as proof.In 2008, he was elected as a Member of the Italian Parliament in the Chamber of Deputies with Silvio Berlusconi's centre-right party, The People of Freedom. In 2010, he joined, with the other 32 deputies and 10 senators, the Gianfranco Fini's new party Future and Freedom. He left parliament in 2013.
On August 28, 2012, in Filicudi a similar event is repeated which sees Barbareschi attack again with kicks and punches the journalist Filippo Roma and hit his cameraman.
