If there is one thing Avengers director Joss Whedon knows how to do, it’s assemble people. To that end, the filmmaker has a new, pro-Hillary super PAC launching today called Save the Day, which kicked off with a video in which a slew of celebrities tell you to get out and vote. The public service announcement spoofs nonpartisan efforts like Rock the Vote that encourage you to head to the polls to support the candidate of your choosing—except in Whedon’s version, those celebrities point out that maaaybe you shouldn’t vote for “a racist, abusive coward who could permanently damage the fabric of our society.”

Having this many celebrities in a PSA is usually reserved for “diseases and ecological crises,” but the video still boasts quite a bit of star power: Robert Downey Jr., Scarlett Johansson, Keegan-Michael Key, Julianne Moore, Nathan Fillion, Don Cheadle, Neil Patrick Harris, Yvette Nicole Brown, Leslie Odom Jr., and many, many more lend their famous (and in some cases, not-so-famous) faces to the cause.

Whedon has never been shy when it comes to politics, and though the video doesn’t name any names, it’s pretty clear who he’ll be voting for on Nov. 8. So get out and vote, if not for our country’s sake, then at least for Mark Ruffalo’s.
