EXTRAS:
Ingrid Bergman was one of the greatest actresses from Hollywood's lamented Golden Era. Her stunning natural beauty and immense acting talent made her one of the most celebrated figures in the history of American cinema. Great performances result from an actor’s collaboration with great directors, and Ingrid Bergman went further—and sacrificed more—than did any other actor in order to work with a true cinematic genius, Italian director Roberto Rossellini. While at the peak of her popularity, Bergman was so taken upon seeing Rossellini’s Italian neorealism films,
Rome,
Open City (1945)and
Paisan (1946), that she sent the director a letter, introducing herself and offering her talents in any film of his choice.
Ingrid Bergman was born on August 29, 1915 in Stockholm, Sweden, to a German mother who died when she was only two, and a Swedish father that passed away when she was twelve. After finishing formal schooling, she enrolled at the Royal Dramatic Theatre School in Stockholm but decided that screen acting was her passion. In 1936, Bergman appeared in the Swedish film, Intermezzo, which caught the eye of American producer David O. Selznick, who signed her to a contract. She moved to California and reprised her original role in an English language remake of Intermezzo (1939). The film was a hit and so was Bergman.
Her beauty was infectious and her acting and attention to craft indicated to moviegoers that her films represented a tradition of quality. Her impressive performances and awards were seemingly endless, appearing in Casablanca (1942), For Whom the Bell Tolls (1943), an Oscar-winning performance in George Cukor’s Gaslight (1944), and three films by Alfred Hitchcock. But it was her portrayal of a nun in Leo McCarey’s The Bells of St. Mary's (1945) and title role in Joan of Arc (1948) that cemented her off-screen image to the public as a moralistic, saint-like character which she played on the screen. But that was before Rossellini.

In 1949 Bergman arrived in Italy to film
Stromboli (1950) with Rossellini, and they quickly fell in love with each other. Bergman left her husband, Petter Lindström, and their young daughter, Pia Lindström, to live with Rossellini. When she and Rossellini made
Stromboli, Bergman was pregnant with his child. She divorced Lindström, but the divorce hadn’t yet come through, and America's "moral guardians" were outraged. She decided to remain in Italy, where a son was born, followed by twins, Isotta and Isabella Rossellini, who became a world-famous model and actress, and later spouse of American director Martin Scorsese.
Bergman was denounced in the press, in pulpits, and even in the Senate; local officials called for boycotts on all of her films, and it was beside the point whether she was persona non grata in Hollywood, because she had no intention, at the time, of working in Hollywood again.
Together, Bergman and Rossellini made six films that are works of both sociopolitical concern and metaphysical melodrama, each starring Bergman as a woman experiencing physical dislocation and psychic torment in post-World War Two Italy.
In 1957 they divorced, partly due to Rossellini not wanting her to work with any director other than himself, which caused trouble in their work together and marriage. Plus, Rossellini had an extramarital affair with the Indian screenwriter Sonali Senroy DasGupta whom he later married.
Ingrid continued to make films in Italy and finally returned to the English-speaking world in the title role in Anastasia (1956) to applause and forgiveness, and winning her second Academy Award. She continued to bounce back and forth from Europe and Hollywood, culminating in her final big-screen performance in 1978's Swedish film Autumn Sonata, directed by fellow Swede Ingmar Bergman, where she received her final Academy Award nomination. Ingrid Bergman died from cancer in 1982 on her 67th birthday.
