Filmmaker Michael Moore has been working on an October surprise all of his own. 

The “Bowling for Columbine” director announced on Twitter Tuesday that he’d been working in secret on a new documentary all about Republican nominee Donald Trump -- and he’s premiering it right away. 

The film, “Michael Moore in TrumpLand,” will screen Tuesday evening at New York City’s IFC Center. Tickets for the event will be handed out for free on a first come, first served basis starting one hour before the film’s 9:30 p.m. showtime. 

The film’s synopsis on the IFC Center’s website reads: “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.”

Moore has been vocal all throughout the 2016 presidential race, cautioning about the rise of Trump and correctly predicting the “Celebrity Apprentice” star would clinch the GOP nomination. 

In August, the filmmaker published an essay claiming that Trump was self-sabotaging because he never actually wanted to be president and had instead entered the race in order to improve his negotiating position with NBC.
