Beijing — The big upset at the 2019 Oscars by "Green Book" was a victory for its Chinese investor Alibaba Pictures, but there is no guarantee the best-picture winner will be a hit when it opens this week in China where viewers prefer blockbusters.

Set in the south of the United States in the 1960s, the film follows the friendship of a working-class Italian-American man who was a driver and fixer for an African-American pianist. — Reuters
