Michael Moore secretly made a movie about Donald Trump, and now he's premiering it.  After teasing for weeks on his Twitter account that he had a surprise, the documentary filmmaker announced Tuesday that he'll premiere "TrumpLand," at NYC's IFC Center. General admission screenings begin Wednesday, 10/19.

"See the film Ohio Republicans tried to shut down," a synopsis on the IFC Center website said. "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."

Moore has been a loud critic of Trump and his run for president. Shortly before speaking to Business Insider in December, Moore visited Trump Tower with a sign that read "We Are All Muslim" in protest of Trump's calls to bar all Muslims from entering the U.S. Moore also wrote an open letter to Ivanka Trump pleading that she end her father's campaign. He then argued in The Huffington Post that Trump never actually wanted to be president.

But this is the filmmaker's biggest step yet in trying to disrupt Trump's run for president.
