Fifteen years since its original release, Michael Moore’s Bowling for Columbine is still as potent and staggeringly resonant as it ever was. How could it not be, when mass shootings and slack gun control laws are still a persistent problem across the country? Days before the 18th anniversary of the Columbine High School massacre on April 20, a man in Cleveland shot another man on Facebook Live, after claiming to have just killed dozens more. Only a few days before that, a man barged into a classroom and killed a teacher (his estranged wife) and an 8-year-old boy in San Bernadino—the same city where, in 2015, 14 people were shot and killed at an office Christmas party.

Both recent shootings weighed heavily on Moore’s heart before an anniversary screening of his famous documentary at the Tribeca Film Festival on Thursday night.

“We could release this film again this Friday, sadly, and it would probably be every bit as relevant,” he said while presenting the movie, before rattling off some disheartening statistics about the uptick in mass shootings since Columbine.

After the film, Moore sat down with legendary documentarian D.A. Pennebaker (still delightfully spry at 91 years old) to discuss the film’s legacy, though the conversation more often than not turned to a different troubling topic: Donald Trump. In Columbine, Moore often reiterates that Americans live in a constant state of fear, a national trait that played a big part in the 2016 election.

“Ignorance leads to fear,” Moore said on Thursday. “Fear leads to hate—Trump knew that part of the equation very well—and hate leads to violence. Or to use your ballot as an act of violence against the people you hate.”

He continued, saying that he feared that the country was moments away from its “own Reichstag fire,” the event that helped solidify the ascent of Nazi Germany.

“There will more than likely be some sort of terrorist act in this country,” Moore said. “I fear that [Trump] will use that to such an awful extent. We have to fight then when it happens.”

Pennebaker likened Trump to a man who can’t drive, but gets a Ferrari and then races off with it. “With your child in the front seat,” Moore quipped.

The conversation did eventually flow back toward gun control. Moore recalled that when he originally made Bowling for Columbine, there were ratings concerns over showing actual footage from the Columbine shooting (the doc shows security-camera footage from inside the school that captures the hysteria in the cafeteria after the shootings began but does not show any of the killings). He then brought up the deadly Sandy Hook shooting, where 20 schoolchildren and six adults were murdered by a single gunman. Moore says that he catches “a lot of grief” for including the Columbine footage, and emphasizes that he feels deeply for the mourning parents and family members. But he also thinks that if there was footage of the Sandy Hook killings, gun control changes would be made.
