| Hillary Clinton was supported by a host of celebrities - but failed to win the presidency |
It is meant to be a heartfelt appeal from some of the US's most recognisable faces.
Actors Martin Sheen and Debra Messing are joined by a host of other celebrities - including musician Moby - to ask Republican electors to not cast their vote for President-elect Donald Trump on 19 December.
The argument put forward in the Unite for America clip is simple - Mr Trump is not fit to be president of the United States, and therefore members of the Electoral College should block his entry to the White House.
"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 explains in the video.
Celebrity power
Mr Trump, the celebrities continue, is not "highly qualified for the job" - and therefore the electors could, and should, prevent him from taking office.
In theory, the Electoral College could do this: It would take 37 Republican electors to vote for someone other than Mr Trump - thereby taking the party under the 270-vote threshold necessary for victory - to technically block his path to the White House. It is the latest stance taken by celebrities against Mr Trump's impending leadership. Others have been less direct - designers refusing to dress future First Lady Melania Trump, or rejecting offers to sing at the inauguration.
In stark contrast to his predecessor Barack Obama, only one A-list celebrity - Kanye West - has publicly endorsed Mr Trump since his election.
But in reality, how much does any of this matter - and how effective is such a direct plea to a group of Republicans?
