With Vampiro romano, Leonardi made his last experimental film before switching to collective videomaking with the group Videobase, which focused on political investigation and counter-information. "We are all vampires. We live and move forward, intellectually and emotionally, thanks to the contribution – the 'blood' – of the people closest to us."
