Depending on who you ask, Green Book is either the pinnacle of movie magic or a whitewashing sham. The film, which was released last fall, depicts the burgeoning friendship between a black classical pianist and his Italian-American driver as they travel the 1960s segregated South on a concert tour. But while Green Book is a serious contender to win Best Picture at the Oscars, its road there has been riddled with missteps and controversies over its authenticity and racial politics.
