The segregation-era road-trip drama "Green Book" was crowned best picture at the Academy Awards. Mahershala Ali was named best supporting actor for playing a black pianist touring the segregated US South in the 1960s - his second Academy Award in three years. Filmmaker Alfonso Cuaron walked away with his career's second Oscar trophy for direction for his monochrome memory piece "Roma", furthering Mexican dominance at the Academy Awards. Cuaron succeeded last year's winner, fellow countryman Guillermo del Toro, in the category where he faced off with Yorgos Lanthimos ("The Favourite"), Spike Lee ("BlacKkKlansman"), Polish helmer Pawel Pawlikowski ("Cold War") and Adam McKay of "Vice".
