Example Input: Question: Around what age was Ingmar Bergman when he rose to prominence? Passage:The famous and influential Swedish filmmaker, Ingmar Bergman, rose to prominence in the fifties. He began making films in the mid-forties, and in 1955, he made Smiles of a Summer Night, which brought him international attention. A year later, he made one of his most famous films, The Seventh Seal. In the 1960s, Bergman won the Academy Award for Best Foreign Language Film for two consecutive years, with The Virgin Spring (Jungfrukällan) in 1960 and Through a Glass Darkly (Såsom i en spegel) in 1961. He won the award again in 1983, for the early twentieth-century family drama Fanny and Alexander (Fanny och Alexander). Bergman has also been nominated for the Best Picture award once, with the 1973 Cries and Whispers (Viskningar och rop), the story of two sisters watching over their third sister's deathbed, both afraid she might die, but hoping she does. The film lost to The Sting, and oddly enough, it was not nominated in the Foreign Language Film category. It also gave Bergman the first of three nominations for Best Director. Ingmar Bergman also won four Golden Globe Awards for Best Foreign Language Film.
