VIGGO MORTENSEN and Mahershala Ali star in “Green Book,” with won three Oscars including Best Picture at Sunday’s 91st Academy Awards. Ali won for Best Supporting Actor.

The 91st annual “Oscars” on Sunday night didn’t have a host, but there was no lack of surprises or diversity.

“Green Book,” somewhat of an underdog, took the Oscar for best picture, and also triumphed with the awards for original screenplay and supporting actor – Mahershala Ali.

Those three wins were matched by three Oscars each for “Roma” and “Black Panther.” But movie with the most metal was “Bohemian Rhapsody” with a win for best actor – Rami Malek – and three more.

“Green Book” was based on the true story of a rough-hewn Italian-American hired to serve as driver and bodyguard to a refined African American pianist on a tour through the segregated South in the early Sixties.
