Ughh, stick to acting.

Via The Hill:

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.”

In a video tied to the super PAC’s Wednesday launch, more than 20 celebrities share a message directly to the camera.

“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.

“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.”
