Lee called the President of the United States "that motherf-er" in the White House in a lengthy, curse-laden speech during the Tuesday press conference for his new film "BlacKkKlansman", which premiered Monday at the Cannes Film Festival to a prolonged standing ovation (check out the trailer above).

Before inserting footage of the vehicle that ploughed through crowds in Virginia, killing counter-protester Heather Heyer, Mr Lee said he telephoned Heyer's mother. Based in the early 1970s, the picture is centered around Ron Stallworth (John David Washington), who becomes is the first African-American detective to serve in the Colorado Springs Police Department.
The 61-year-old filmmaker said that following the violence in Charlottesville, the US president had the opportunity to denounce the Ku Klux Klan and the alt-right.
An official trailer for BlacKkKlansman, which is directed by Spike Lee and produced by Jordan Peele, was released this week by Focus Features.
The 61-year-old filmmaker said Mr Trump - whom he refused to call by name - had "a chance to say we are about love and not hate", and sharply criticised him for not denouncing the KKK.
"We look to our leaders to give us direction... and I like to say this right-wing bullshit is all around the world".
Lee referred to Charlottesville as an "ugly, ugly, ugly blemish on America", while making sure to remind the global media at Cannes that the racism depicted in "BlacKkKlansman" doesn't only exist in the United States.
Lee criticized Trump's response to a white nationalist rally Charlottesville, Va. last summer, and reportedly referred to the president as a "mother--".
"I was not going to put that murder scene in the film without her blessing", said Lee. "It's not a black, white, or brown [problem], it's everybody", he said. "We have to wake up and we can't be silent", an exhausted Lee told reporters. "And that motherf**ker did not denounce the Klan, the alt-right, and those Nazi f**kers", Lee said. I go to bed thinking about it.
He hopes "BlacKkKlansman" "shakes people from their slumber". "We're on the right side of history with this film".
