[on Renato Polselli] Polselli was neither a genius nor a madman. He had great ambitions, but I think that he only made modest movies. Renato was an old school director. he was born in 1922, with all the prejudices of his time on women, and actress in particular. He was a decent director and a modest screenwriter.
