A swathe of celebrities have united for a video urging members of the Electoral College to vote against their states and select a presidential candidate other than Donald Trump.
The video - which included the likes of Hollywood actor Martin Sheen, Breaking Bad's Bob Odenkirk, Will and Grace star Debra Messing, and music producer Moby - urges each College member to become an "American hero" by voting against Trump.
"Our Founding Fathers built the Electoral College to safeguard the American people from the dangers of a demagogue and to ensure that the presidency only goes to someone who is to an 'eminent degree endowed with the requisite qualifications,'" Sheen said.
"By voting your conscience, you and other brave Republican electors can give the House of Representatives the option to select a qualified candidate for the presidency."
It would be an incredible thing if such an event were to take place, as the 538 members of the Electoral College generally vote the same way as their state.
The only occasion in history that College members altered the course of an election was back in 1836, when 23 Virginia electors voted against their state - they were overruled by the Senate, and the original election winner remained the victor.
For Hillary Clinton to see the election result turn in her favour, it would require at least 30 members to go against their state's wishes, which would be the largest number of votes overturned in history.
US documentary maker Michael Moore last week urged Electoral College members to go against their state - and predicted they would.
"Would you not agree, regardless of which side of the political fence you're on, that this has been the craziest election year?" he asked while appearing on Seth Myers's late-night show.
"Nothing anyone predicted has happened - the opposite has happened. So is it possible, just possible, that in these next six weeks, something else might happen - something crazy, something we're not expecting?"
The Electoral College is made up of state officials and senior party figures from the Republicans and Democrats, and thanks to America's convoluted election system, US citizens don't actually decide who becomes President - members of the Electoral College do.
On December 19, the College will vote for whom they want for President, and there remains a possibility they could yet turn their backs on Mr Trump.
