After cleaning up at every major movie bash so far this award season Joaquin Phoenix looks odds on favourite to be named the Oscar’s best actor.
But his all-conquering role in Joker has been no laughing matter for the star, who has used his acceptance speeches over the past month as a platform for various campaigns.
One of those issues is climate change and days before the Academy Awards he is the star of a new short film, part funded by the Extinction Rebellion.
This is how Joaquin led a very different Oscar’s campaign.
