Joaquin Phoenix denounced the film industry last night as he called on it to “do the hard work to truly understand systemic racism”.

Phoenix, named best actor at the Baftas for his role in Joker, said that he felt “conflicted [winning the award] because so many of my fellow actors who are deserving don’t have that privilege”.

Referring to the all-white acting shortlists and reiterating the Duke of Cambridge’s call that the industry needed more diversity, Phoenix said: “We send a very clear message to people of colour that you are not welcome here, people who have contributed so much to our medium and industry which we benefit from.

“I am part of the problem,” he added. “I have not done everything in my power to ensure that all the sets I work on are inclusive.

“I think it is the obligation of the people who have created and perpetuate and benefit from a system of oppression to be the ones to dismantle it. So that is on us.” He made his comments after the chairwoman of Britain’s Time’s Up campaign said that Bafta was in the last chance saloon.
