A bunch of Hollywood stars got together to make a public service announcement urging people to vote.

Innocent enough, right? Wrong. It’s actually an anti-Trump announcement.

“We cannot pretend both sides are equally unfavorable.”

“Avengers” director Joss Whedon created a super PAC with $1 million of his own money — along with the video — and it’s dedicated to helping elect Hillary Clinton. For the effort, he assembled Mark Ruffalo, Robert Downey Jr., Scarlett Johansson, James Franco, Neil Patrick Harris, Jesse Williams, and some other not-so-recognizable faces.

Quick cuts show each person extolling the importance of voting. Then it takes a Harry Potter-esque turn — as stars blatantly attack Trump without ever naming him.

“You only get this many famous people together when the issue is one that truly matters to all of us,” say “SNL” star Taran Killam and “Fresh Off the Boat” actor Randall Park.

The celebs go on to list the causes important enough for celebrities to stump for — like a disease, an ecological crisis or, as Don Cheadle, says a “racist abusive coward who could permanently damage the fabric of our society.”

And Martin Sheen adds, “We cannot pretend both sides are equally unfavorable.”

The carrot being dangled, so to speak, for people who do vote? Ruffalo promises to do a nude scene in his next movie.

“They should just vote ’cause it matters,” Ruffalo says.

Variety says the video is an “irreverent riff on the overly earnest celebrity PSA” — but it comes off as just another overly earnest PSA.

Whedon told BuzzFeed that the video  — titled “Important” — is the first of a series of several short films that will help bring attention to his Save the Day campaign. Seven have already been shot; five more are planned. He said he had no trouble asking stars to take part.

“There is almost nobody that I wouldn’t approach to say, ‘If you can pitch in, do it now,'” he said. “It was pretty much the same spiel to everybody: ‘Doing a voting PSA to help get out the vote and stop orange Muppet Hitler.'”

Another dig at Trump.
