Filmmaker Michael Moore has some harsh truths for America following president-elect Donald Trump’s astounding victory and he shared them in a helpful five-point plan.

The controversial director, known for documentaries such as Fahrenheit 9/11 and Bowling for Columbine, took to Facebook after the result was revealed to post a “morning after to-do list”.

In the post, which has been shared more than 150,000 times, Moore urged his nearly 2 million Facebook fans to reclaim the Democratic Party and fire the pollsters who got their predictions so very wrong.

Most notably, Moore asked Americans to “stop saying they are ‘stunned’ or ‘shocked’,” and instead find hope in the popular vote, which was won by Democratic candidate Hillary Clinton.

“If you woke up this morning thinking you live in an effed-up country, you don’t. The majority of your fellow Americans wanted Hillary, not Trump,” Moore wrote.

The 62-year-old pointed to the United States’ “arcane, 18th-century insane” electoral college system as the reason for Mr Trump’s election.

The electoral college is the body that gets to elect the president. US citizens are unable to directly elect the president and instead must vote for electors in their state, who then pledge to vote for particular candidates.

Thus, a candidate must win overall states – each of which count for a particular amount of electoral votes – rather than individual popular votes.

“Until we change that, we’ll continue to have presidents we didn’t elect and didn’t want,” Moore reasoned.

Moore was one of the few media figures who predicted a Trump victory, penning an essay on his website back in July titled ‘Five reasons Trump will win‘.

“I have even more awful, depressing news for you: Donald J. Trump is going to win in November,” Moore warned.

“This wretched, ignorant, dangerous part-time clown and full-time sociopath is going to be our next president.”

After being proven right, Moore accused those who doubted this outcome of ignorance.

“You were in a bubble and weren’t paying attention to your fellow Americans and their despair,” he said to his followers.

“Trump’s victory is no surprise. He was never a joke. Treating him as one only strengthened him.”

Moore, who pledged support for Democratic candidate Bernie Sanders prior to Ms Clinton’s nomination, has a complicated relationship with Mr Trump.

The pair first met in 1998 whilst appearing on a talk show together.

Moore was told Mr Trump was nervous to appear alongside him because of his reputation for asking hard-hitting questions, so he tried to reassure him before the show.

“In the years since, I’ve thought, jeez, he is good—because he played me,” Moore said. “I didn’t go after him or his real estate here or any of that stuff.”

In August, Moore revealed, citing anonymous sources, that Mr Trump was “self-sabotaging his campaign because he never really wanted the job in the first place”.

In October, he released a surprise documentary, Michael Moore in TrumpLand, a one-man show filmed over two days in the key swing state of Ohio.

Surprisingly, Mr Trump responded by tweeting a clip from the film and saying he agreed with Moore.

However, the clip Mr Trump shared was edited and only included praise for the Republican candidate.

“They see that the elites, who ruined their lives, hate Trump. Corporate America hates Trump. Wall Street hates Trump. The career politicians hate Trump,” Moore says in the clip.

“The media hates Trump – after they loved him, and created him, and now hate him. Thank you, media. The enemy of my enemy is who I’m voting for on November 8th.

“Trump’s election is going to be the biggest ‘f*** you’ ever recorded in human history. And it will feel good.”

I agree, @MMFlint– To all Americans, I see you & I hear you. I am your voice. Vote to #DrainTheSwamp w/ me on 11/8. https://t.co/D7nBwkogBb

Moore responded by slamming Mr Trump for sharing the doctored clip and missing the point of his film, which he described as “a funny love poem to Hillary”.

The real ending of the clip Mr Trump shared showed Moore explaining a Trump victory would feel good momentarily but would inevitably lead to regret – similar to that experienced by British people after the Brexit vote.

I can't keep taking Trump's voters $$. Folks, your leader has deceived u again: "Michael Moore In TrumpLand" is a funny love poem to Hillary
