Filmmaker Michael Moore is launching the national release of his new documentary “Where to Invade Next” on Friday, which is said to be both his happiest and “most subversive” movie yet.

In the film, Moore travels to countries throughout Europe and also Tunisia to “pry loose from them the tools they’ve been using to make their countries happy, shiny places,” he writes, with the goal of “show[ing] millions of Americans what these countries have been hiding from us.”

Such tools range from eight weeks paid vacation in Italy, to a year of paid maternity leave in Scandinavia, to women with “true equality and power” in Tunisia, to trusting prisons in Norway.

Moore, who is known for such works as “Bowling for Columbine” and “Capitalism: A Love Story,” penned an open letter to supporters last week explaining how a recent bout of pneumonia and subsequent hospital stay forced him to cancel all television appearances promoting the film.

“I have to be honest,” Moore writes. “I’m now worried about my film’s release. I can’t fly, I have to recover, and [on February 12th] this great movie I’ve put so much of my life into is going to open in theaters — with little or no assistance from me.”

Then, in a direct appeal to his fans, Moore then calls for a “cobbled-together ‘army’ of grassroots foot soldiers” to help spread the word about the new movie, which he says “will inspire people to think about things in a different way.”

“Last week, laying in the hospital, I watched one Presidential candidate attack the candidate from Vermont for his ideas being ‘unrealistic,’ ‘pie in the sky,’ and ‘ideas that sound good on paper, but aren’t going to happen,’ Moore said. “The truth is, all these great ‘ideas’ — free universal health care, free university, free day care, taxing and policing hedge fund millionaires—have already happened in nearly every other industrialized country in the world! And I have the evidence — and the film—to prove it!”

“You are going to be seriously f***ed up by this film,” Moore adds. “It’s unlike anything I’ve ever done.”

Intercept columnist Jon Schwarz, who previously worked with Moore, argues that “Where to Invade Next” is the filmmaker’s “most subversive movie” yet.

“On its surface, ‘Where to Invade Next’ seems to be a cheerful travelogue as Moore enjoys an extended vacation, ‘invading’ a passel of European countries plus Tunisia to steal their best ideas and bring them back home to America,” Schwarz writes.

But, he adds, by the end of the film, “after seeing working-class Italians with two months paid vacation, Finnish schools with no homework and the world’s best test scores, Slovenians going to college for free, and women seizing unprecedented power in Tunisia and Iceland — you may realize that the entire movie is about how other countries have dismantled the prisons in which Americans live: prison-like schools and workplaces, debtor’s prisons in order to pay for college, prisons of social roles for women, and the mental prison of refusing to face our own history.”

“You’ll also perceive clearly why we’ve built these prisons,” Schwarz says. “It’s because the core ideology of the United States isn’t capitalism, or American exceptionalism, but something even deeper: People are bad. People are so bad that they have to be constantly controlled and threatened with punishment, and if they get a moment of freedom they’ll go crazy and ruin everything.”

The secret message of “Where to Invade Next” is that America’s had it wrong all along about human beings. You and I aren’t bad. All the people around us aren’t bad. It’s okay to get high, or get sick, or for teenagers to spend every waking moment trying to figure out how to bonk each other. If regular people get control over their own lives, they’ll use it wisely rather than burning the country down in a festival of mindless debauchery.
