Spencer was born in Naples in 1929 as Carlo Pedersoli, but changed his name early in his career to better market himself. “Spencer” was a nod to the actor Spencer Tracy; he chose “Bud” because he loved Budweiser beer, according to Euro News.
Spencer had a colorful career onscreen and off. He appeared in more than 20 films, but also dabbled in professional swimming — he was the first Italian to swim a hundred meters of freestyle in under a minute — and, later, aviation. An attempted stint in politics proved unsuccessful.
The BBC said he died painlessly in Rome.
