One half of the Farrelly directing duo, Peter Farrelly, has departed from the couple's proclivity for comedy to deliver a heartfelt account of an unlikely friendship in the face of racial adversity.
Taking its title from a guidebook designed for blacks travelling through America's racist South, Green Book is set in the 60s and focusses on two New York men.
Tony "the lip" Vallelonga is a sloven, working-class family man played by Viggo Mortensen (Captain Fantastic), and Dr Don Shirley is an educated classical pianist with impeccable social manners and a clipped sense of decorum, played by Mahershala Ali (Moonlight).
They are socially, racially and ideologically worlds apart, however, they are forced together through a mutual work arrangement that pits Tony as the driver and hired muscle to guide Don though the more unsavoury (racially speaking) parts of the southern states.
