She won the Golden Globe, BAFTA and Screen Actors’ Guild award for her portrayal of Judy Garland, in the movie Judy.
She has 1/20 odds at present, while Scarlett Johansson follows with 16/1 odds, Cynthia Erivo at 25/1, and Saoirse Ronan at 33/1.
Charlize Theron, who is nominated for her work in Bombshell, has not won an award of this type yet, and looks unlikely to win this time with 50/1 odds.
Who will win Best Actor at the Oscars?
If the previous awards ceremonies are anything to go by, this award is in the bag for Joaquin Phoenix.
