Celebs speak out against Trump

A bevy of big names — including Robert Downey Jr., Scarlett Johansson, Julianne Moore, Don Cheadle and Mark Ruffalo — are coming together to speak out against Donald Trump and urge voters to head to the polls in November.

Save the Day, a new super PAC launched by “The Avengers” writer and director Joss Whedon, describes itself as “a short-form digital production company dedicated to the idea that voting is a necessary and heroic act.”

“On Tuesday, Nov. 8, this country will make one of the most important decisions in its history,” Downey of the “Iron Man” series and a number of other entertainers say.

“You might think it’s not important. You might think you’re not important,” says “Spotlight” actor Mark Ruffalo.

“But that’s not true, says “Key & Peele” comedian Keegan-Michael Key.

The tongue-in-cheek video pokes fun at traditional celebrity-filled public service announcements, with stars chiming in, “The only way we can prove that to you is by having lots of famous people — just a s— ton of famous people — repeating how important it is.”

Without naming him, the spot targets Trump, the GOP presidential nominee.

“Captain America: Civil War” actor Cheadle says the issue is important because it involves a “racist, abusive, coward who could permanently damage the fabric of our society.”

“Do we really want to give nuclear weapons to a man whose signature move is firing things?” asks “Hamilton” star Leslie Odom Jr.

“We can end this nightmare before it begins,” Julianne Moore says.

“West Wing” president Martin Sheen, Neil Patrick Harris, Rosie Perez, Stanley Tucci and “Saturday Night Live” cast member Taran Killam also make cameos.

In an interview with BuzzFeed, which first reported the story, Whedon revealed his pitch to convince the Hollywood heavyweights to participate: “It was pretty much the same spiel to everybody: ‘Doing a voting PSA to help get out the vote and stop orange Muppet Hitler.’”

Whedon says while one star was hesitant, saying, “I didn’t expect this to be quite so partisan. I don’t want to alienate half my fan base,” they all ended up appearing in the video.
