Going a long way from “Mr. Brightside,” the Killers take a powerful stand against President Donald Trump’s ongoing fight for a US/Mexico border wall in their new single, “Land of the Free.”

And they got “BlacKkKlansman” director Spike Lee to bring his vision to the song’s haunting video.

Backed by a gospel choir and some thumping drums, frontman Brandon Flowers sings, “Down at the border/ They’re gonna put up a wall/With concrete and rebar steel beams/High enough to keep all those filthy hands off of our hopes and dreams/People who just want the same thing we do/In the land of the free.”

“I think it is a very important time right now, and ‘enough is enough’ was basically where it came from,” Flowers told Beats 1 on Apple Music about the song, which also tackles racism, mass incarceration and the gun debate in America. “It started in my mind around when Sandy Hook happened and, as a father, how that affected me, and then it just started stacking up.

“It was things like Eric Garner, Trayvon Martin, things like what’s happening at the wall. You know, this stuff just didn’t seem to be in harmony with the values that I believe my country was founded on.”

The video — which the Killers gave Lee full creative control over — was shot over a few weeks at the end of 2018. It captures migrant families traveling by foot to the border, attempting to make their way into “the land of the free.”

There are graphic depictions of migrants being chased by border patrol — with smoke and tear gas being deployed against them — and being held in detention centers. The Killers themselves are not featured in the video.

“I never thought that I would be a part of a Spike Lee joint,” Flowers told Beats 1 on Apple Music. “I had just recently seen ‘BlacKkKlansman’ and watched ‘Do the Right Thing’ on an airplane. It was just like, ‘We got to ask him to do this video’ … And it was just an incredible thing to collaborate with him.

“He’s a master, obviously. Some of these issues are obviously very close to his heart, and he just hit it out of the park.”
