Michael Moore is set to debut his secret documentary about GOP presidential Donald Trump Tuesday night in New York City.

Moore has been privately working on a documentary about Trump called Trumpland, which will debut at the IFC Center in New York Tuesday night at 9:30 p.m. ET. Tickets are free, with the box office opening up at 8:30 p.m.

"See the film Ohio Republicans tried to shut down. Oscar-winner Michael Moore dives right into hostile territory with his daring and hilarious one-man show, deep in the heart of TrumpLand in the weeks before the 2016 election," the movie synopsis reads.

Trumpland is expected to begin running regularly starting Wednesday, at the IFC Center.

Moore is famous for such controversial political documentaries as 2002's Bowling for Columbine and 2004's Fahrenheit 911, about the 1999 Columbine massacre and the George W. Bush administration, respectively. Other notable documentaries from the filmmaker include 1989's Roger & Me, about General Motors transferring its business from Flint, Mich. to Mexico, 2007's Sicko, about the American health care system, 2009's Capitalism: A Love Story, exploring the late-2000s financial crisis, and 2015's Where to Invade Next, which compares Europe's social and economic structures with America's.

Moore has been promoting Trumpland this week on his Twitter page:

The filmmaker has been an outspoken opponent of Trump over the past year, though he wrote a blog post this summer on why he thinks he will win on election night:

"I am sorry to be the bearer of bad news, but I gave it to you straight last summer when I told you that Donald Trump would be the Republican nominee for president. And now I have even more awful, depressing news for you: Donald J. Trump is going to win in November," he wrote. "This wretched, ignorant, dangerous part-time clown and full time sociopath is going to be our next president. President Trump. Go ahead and say the words, 'cause you'll be saying them for the next four years: 'PRESIDENT TRUMP.'"
