IT’S the controversial documentary which is promising to make a major impact on Donald Trump’s presidency.

And controversial filmmaker Michael Moore promises it will be key in dissolving Trump’s Teflon shield.

Moore, who successfully predicted Mr Trump would win the US election, has been secretly working on a new documentary Fahrenheit 11/9 which explores the President’s election win.

“Yes, I’m making a movie to get us out of this mess,” the award-winning filmmaker said on Twitter alongside a link to an article about the film on Variety magazine’s website.

According to the site, film producers Bob and Harvey Weinstein have acquired the global rights to the film through one of their companies, Fellowship Adventure Group, which produced Moore’s Fahrenheit 9/11.

In a statement given to USA Today, Moore wrote that no matter what you throw Trump, it hasn’t worked.

“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.”

The statement from Bob and Harvey Weinstein adds that it “is expected to be key in dissolving Trump’s ‘Teflon’ shield and, in turn, his presidency.”

The name of the leftist filmmaker’s latest documentary stems from the date the results of last year’s presidential election were finalised, November 9, 2016.

The vote itself took place the day before.

It comes more than a decade after Moore first shot to fame with Fahrenheit 9/11, a political documentary about the presidency of George W. Bush in the aftermath of September 11 and the wars in Afghanistan and Iraq.

The film earned him the Palme d’Or prize at the Cannes film festival in 2004.

During the 2016 presidential election, Moore sought to mobilise public opinion against Mr Trump and was one of the very few public figures to say the then-candidate stood a strong chance of winning.

Three weeks before the election, he rushed out a surprise documentary, Michael Moore in Trumpland, an ode to Democratic candidate Hillary Clinton that he made in just 12 days.
