"Motherfucker": that's how director Spike Lee (repeatedly) described Donald Trump yesterday at Cannes Film Festival, as part of a broader criticism of the way that the United States president dealt with the deadly neo-Nazi riots in Charlottesville, Virginia, last year.
"We have a guy in the White House - I'm not gonna say his f**king name - who defined that moment not just for Americans but the world", said Lee. "It was a defining moment, and he could have said to the world, not the United States, that we were better than that".
The 1979-set film, loosely based on a true story, is about black police detective Ron Stallworth (played by Denzel Washington's son John David Washington) and a Jewish detective (Adam Driver) who together infiltrated a Ku Klux Klan cell in Colorado.
The film ends with footage from the protests in Charlottesville, where a woman was killed after a man plowed his auto into a crowd of counter-protesters during the "Unite the Right" rally.
The ending scenes, which were added after the film already wrapped, also include Trump's televised response to the Charlottesville unrest, with the final image of an upside-down American flag.
That was too late for Lee: "This film to me is a wake-up call", he said.
"It's an ugly, ugly, ugly blemish on the United States of America", Lee said at the press conference for the film.
'Produced by the team behind the Academy-Award® winning Get Out, BlacKkKlansman offers an unflinching, true-life examination of race relations in 1970s America that is just as bracingly relevant in today's tumultuous world'. I know my heart, I don't care what the critics say or anybody else, but we are on the right side of history with this film. It's all over the world. Now we have our first look at how these events will unfold under Lee's cinematic supervision thanks to the first BlacKkKlansman trailer. We can't be silent. We all live on this planet, and this guy in the White House has the nuclear code.
I think I count seven "motherfuckers".
