British costume comedy The Favourite earned the accolade for Best British Film, Best Actress for Olivia Colman, Supporting Actress for Rachel Weisz, Original Screenplay, Costume Design, Makeup & Hair, and Production Design.
"Reverting back to a world of separation and isolation is not a solution to anything", Cuaron added, at a time when U.S. President Donald Trump is demanding a wall be built on the U.S. border with Mexico.
