Emma Stone and Rachel Weisz respectively play the Baroness Abigail Masham and Sarah Churchill, Duchess of Marlborough in this historical comedy drama directed by Greek filmmaker Yorgos Lanthimos.

The Baroness and the Duchess, who are cousins, are also rivals fighting to be the favourite of the monarch, Queen Anne, played by Olivia Colman ('Hot Fuzz', 'Murder on the Orient Express'). 

As you can expect in a Lanthimos film, things get really nasty, really quickly. 

'The Favourite' competed at Venice International Film Festival this year, where it won the Grand Jury Prize. Olivia Colman won the Volpi Cup for Best Actress.

All of the actresses are expected to be nominated for the Oscars, with Colman standing the greater chance to win.

The film will be released in cinemas in 2019.
