Surprise! Michael Moore debuts TrumpLand movie weeks before election day

Michael Moore has premiered a surprise film discussing the presidential election just three weeks before Americans head to the polls.

Moore debuted Michael Moore in TrumpLand in New York on Tuesday night in front of an audience of his fans.

According to The Hollywood Reporter, the film features Moore speaking about both Republican nominee Donald Trump and Democratic candidate Hillary Clinton on stage earlier this month in Wilmington, Ohio, a hotbed of Trump support.

The liberal documentarian urged the crowd at Tuesday's premiere to vote for Clinton next month.

"If you support Hillary Clinton and you've been doing this end zone dance and celebrating her early victory, you've been helping to defeat her by doing that," he said in introducing the film.

"There's a long tradition of Americans electing people you don't think they're going to elect."

The Hollywood Reporter says the film will screen for one week at the IFC Center in Manhattan beginning Wednesday.

It will also be shown at a theatre in Encino, Calif. Moore said he hopes more theatres will be announced soon. 

"I'm filled with optimism, but I'm gonna be busy every single minute between now and when the polls close. I'm taking this very seriously," the filmmaker said.

The movie is based on the one-man play Moore had planned to mount in Ohio earlier this fall, but the plan was nixed by the venue's board because the project was deemed too controversial. 

No stranger to tying politics to movie projects, Moore released his Palme d'Or-winning doc Fahrenheit 9/11 — a critical look at the presidency of George W. Bush and the invasion of Iraq — when Bush was running for re-election against Democratic Senator John Kerry in 2004. The film, which made more than $220 million US worldwide, is the highest-grossing documentary of all time.
