premise: Departure of a Grand Old Man (Russian: Уход великого старца , translit. Ukhod velikovo startza) is a 1912 Russian silent film about the last days of author Leo Tolstoy. The film was directed by Yakov Protazanov and Elizaveta Thiman, and was actress Olga Petrova's first film.
hypothesis: Olga Petrova's career was launched because of her involvement in the film.
reason: The text says that it was Olga's first film, but it does not state that she went on to have a career as an actress. It could very well be the only film that she was ever in based on the text. I'm sure the system got this wrong because of the "first film" bit.
