Left-wing filmmaker Michael Moore led tens of thousands of protesters and celebrities at an anti-Trump rally Thursday night outside Donald Trump’s New York City International Hotel.

The pre-inauguration rally began at 6:00 p.m. and was streamed live at the liberal website Moveon.org. The event featured speeches from political figures including New York Mayor Bill De Blasio and Minneapolis Mayor Betsy Hodges and actors Alec Baldwin, Robert De Niro, and Mark Ruffalo.

Moore tweeted details for the #WeStandUnited NYC Rally and a link to the live stream.

Other celebrities who joined the protest included Marisa Tomei, Sally Field, Julianne Moore, Cher, Cynthia Nixon, Natalie Merchant and Shaliene Woodley.

Moore told the crowd that America has entered into a “very dangerous” time, after electing a “sociopath.”

“With a lot of work on our part, we will stop this man,” Moore shouted. “He will not last four years.”

“If your rep is a Democrat, tell him/her you expect them to AGGRESSIVELY fight the Trump agenda — and if they don’t, you will work with others to support a true progressive in the Democratic primary in 2018,” Moore added.

Echoing his previous calls to protest Trump, Moore urged the crowd to join him in his “100 days of protest” against Trump.

Before introducing Mayor de Blasio, De Niro read fake tweets he said he expected to see from Trump following his appearance at the rally.

“‘De Niro should give back his Oscars,” De Niro told the crowd. Voting was rigged. There’s only one true Raging Bull and that is Vladimir Putin.'”

“Trump is a bad example of this country, this city,” De Niro said.

Baldwin performed his now-famous Trump impression from Saturday Night Live and encouraged the protesters to fight the incoming administration.

“Donald Trump and Steve Bannon and Mike Pence, and all these people that are part of the Trump administration, they think that you are going to lay down,” Baldwin said. “They don’t realize New Yorkers never lay down.”

MSNBC anchor and leftwing activist Al Sharpton also addressed the crowd.

The rally ended with a rendition of “This Land is Your Land,” which included Cher and was led by singer Natalie Merchant.
