US director Spike Lee has called on the world to "wake up" at an incendiary press conference that saw him repeatedly lambast President Trump, BBC reports.
Trump, he said, had been wrong not to denounce last year's far-right rally in Charlottesville, Virginia at which a female counter-protester died.
Lee is at Cannes with BlacKkKlansman, the true story of a black detective who infiltrated the KKK.
"I hope this film shakes people from their slumber," he told reporters.
"We've been walking around in a daze," he added.
Footage of the moment a white nationalist driver ploughed his car into the crowd is shown at the end of Lee's film, which received a standing ovation at its Cannes premiere on Monday night.
