Samaritani had an enormous talent, which allowed him to take on all the rolls the theatre, opera and ballet demanded, making sure to always be involved in all aspects of his productions even when delegating. From the creation of his "sketches" of the set, which were more like works of art in and of themselves to the smallest change in an extra’s costume, he was a true perfectionist preoccupied with every detail. His productions graced the stage of countless opera houses and theaters, amongst them La Scala di Milano, Teatro Regio of Parma, The Metropolitan Opera House, American Ballet Theatre and the Festival of Two Worlds at Spoleto (Festival dei Due Mondi), where he collaborated for many years, alongside his dear friend, Gian Carlo Menotti.
