Oscars voters clearly loved Green Book but many did not.

The film, which won Best Picture , Best Original Screenplay and Best Actor In A Supporting Role (Mahershala Ali) at the 91st Academy Awards on Sunday night, is based on the true-life friendship between black jazz pianist Don Shirley (Ali) and a white club bouncer named Tony Lip Vallelonga (Viggo Mortensen), which develops after Shirley hires Vallelonga as his driver and bodyguard during a musical tour of the Jim Crow South in the early 1960s.
