Fifty years after activists marched against police harassment on the streets of Notting Hill and were tried as the Mangrove Nine, the U.K. is considering legislation that would curtail demonstrations.

“At this moment, there is a motion that possibly will be passed in Parliament to reduce marches,” said Steve McQueen, creator and director of “Small Axe,” said when he sat down for Variety’s Making a Scene presented by HBO. “What the people of The Mangrove were fighting for is coming under direct challenges today. … So, this makes the scene even more vital than ever.”

The scene that McQueen and actor Shaun Parkes discussed in this video is the landmark moment when demonstrators march through the streets of Notting Hill to fight back against police intimidation in the “Mangrove” installment of Amazon Prime Video’s film anthology series.

“The scene is the heart of the film,” McQueen said. “It’s about people who were frequenting The Mangrove, demonstrating because of police’s constant harassment.”

The film tells the true story of Frank Crichlow (Parkes), a Trinidadian immigrant who opened The Mangrove, a Caribbean restaurant in Notting Hill that doubled as an important meeting place for Black radicals, activists, artists and authors in the 1960s and ’70s. The restaurant soon became the victim of constant police raids, leading to protests and the trial of the Mangrove Nine.

“[The scene] is about the joy of life and the people, and how they made the banners and congregated,” McQueen said. “Of course, at a certain point, the demonstration turns because of the confrontation of the police.”

McQueen said the scene is marked by conjoining two distinct tones: the chaotic panic of the march and the geometric formality of the courtroom.

“What I loved about the courtroom scene is how the gallery in the court became a congregation, and how we as Black people turn that space of law into a space of righteousness,” McQueen said.

While the film portrays violent clashes between police and activists, Parkes said those scenes are necessary in showing the struggle and its long-term impact.

“You need to see it hurts,” Parkes said. “Having a debate and arguing about racism and harassment, it’s all well and good. But I knew that you really needed to see that there’s an effect. It’s not water off a duck’s back.”
