Which actors have won the volpi cup for best actor?

The Volpi Cup for Best Actor is an award presented at the Venice Film Festival to honor outstanding male performances. The source describes its origin, naming after Count Giuseppe Volpi di Misurata, and notes that the number of prizes has varied over time. However, the excerpt does not include a roster of recipients or any specific actors who have received the award. Without further information from additional sources, it is impossible to identify which actors have won the Volpi Cup based solely on the provided evidence.
