Michael Moore pledged Tuesday that his newly revealed documentary about Donald Trump will finally defeat the president.

Production of “Fahrenheit 11/9” ― named for the date Trump was declared president-elect ― has already begun in a “cloak of secrecy,” according to a news release distributed to outlets. The film will explore Trump’s victory over Democratic presidential candidate Hillary Clinton and his turbulent tenure as the commander-in-chief.

“No matter what you throw at him, it hasn’t worked,” the filmmaker said in a statement. “No matter what is revealed, he remains standing. Facts, reality, brains cannot defeat him. Even when he commits a self-inflicted wound, he gets up the next morning and keeps going and tweeting. That all ends with this movie.”

No release date is set, but producers Bob and Harvey Weinstein said Tuesday they had already purchased the rights, Entertainment Weekly noted. The Weinsteins served as executive producers on Moore’s Oscar-nominated “Fahrenheit 9/11,” which examined the administration of former President George W. Bush and its war on terror after the Sept. 11, 2001, attacks.

Moore, who won an Oscar for his gun-violence documentary “Bowling for Columbine,” also has a one-man show expected to open on Broadway this summer. He previously made the film “Michael Moore in TrumpLand,” which he released in October.
