Fahrenheit 9/11, Michael Moore s polemic about George W. Bush and the War on Terror, remains the highest-grossing documentary of all time. If the national mood was splintered when that movie opened in 2004, its nothing compared to what it is now, almost two years into Donald Trump s presidency.

So, naturally, Moore is channeling his most famous film to explore that exact subject: Fahrenheit 11/9 seeks to bring Trump down before Novembers midterm elections.

HuffPost has an exclusive look at the first trailer for Fahrenheit 11/9, a reference to the day Trump was declared the winner of the 2016 election. It juxtaposes footage of Trump rallies and neo-Nazi protests with images of Moore using Flint water to hose down the Michigan governors gated driveway. Roger Stone , Alexandria Ocasio-Cortez , Parkland massacre survivor Emma Gonzlez and a host of others from both sides of the so-called aisle appear in the film.

Ahead of the trailer launch, we sent Moore a handful of questions about Fahrenheit 11/9, which hits theaters Sept. 21. Heres what he had to say about the project via email.
