Steve McQueen warned that people might be “disturbed” by his new film, “Grenfell”which will be shown at London’s Serpentine Gallery next month.

The British director, producer and screenwriter made the 24-minute film six months after the June 2017 fire at Grenfell Tower in North Kensington, which killed 72 people.

After enlisting the support of mourners, survivors and other local residents, the director flew by helicopter in December of that year to the tower, directing the entire film in a single shot.

McQueen’s camera repeatedly circles the block of the working-class housing complex, offering viewers a glimpse into the rooms where people died.

Medical examiners can be seen in the footage checking the area.

Speaking to the Guardian, Steve McQueen said: “You have to understand that the violence in this community was no joke. I didn’t want to let people get away with it.”

“There will be people who will be upset. When you make art … there are certain people you might offend. But that’s how it is,” he emphasized.

For a period of his childhood, Steve McQueen lived in the nearby White City neighborhood, noting that he felt compelled to make the film before officials wrapped the Tower in white plastic in the months after the fire.

“It was almost like a race against time,” he said. “When things are covered up, they get forgotten, or it might be more convenient for people who want to forget it,” he added.

The film will be screened as the community awaits the findings of the investigation, which began in September 2017.

McQueen described what happened as a result of “deliberate neglect,” adding: “It was no accident. There were so many people, so many companies, so many factors… It was all a deliberate act of neglect and, to an extent, greed.”
