Marcello Vincenzo Domenico Mastroianni
December 19, 1996
Marcello was born in Fontana Liri, Italy, but soon his family moved to Turin and then Rome. He enrolled at the University of Rome after World War II.
Mastroianni performed with a local drama troupe, earning raves for an appearance in Angelica which brought him to the attention of director Luchino Visconti , who subsequently cast him in his theater production of As you like it.
In 1960 Marcello became a sensation with La Dolce Vita (The sweet life) by Federico Fellini. It was followed by other classic pictures e.g., La notte (The Night)(1960), Divorzio all'italiana (Divorce—Italian Style)(1961) and 8½ (1963). His reputation worldwide was now as strong as in his native country.
In the late sixties Marcello travelled to Britain to star in Diamonds for Breakfast (1968) , the first of his English-language films in which his performance was not overdubbed.
After several critical and commercial disappointments he returned to form in Una Giornata particolare (1977) as a sensitive homosexual in love with a housewife (Sophia Loren). Mastroianni continued to act until his death and held starring roles in about 120 films over the course of his long career.
