Joss Whedon famously deactivated his Twitter account last year, but he’s back to bring forward an important (and very Whedon-esque) message.

Upon his return Wednesday morning, Whedon made a self-deprecating joke about how the world is basically a dumpster fire now before casually dropping a link to his newest project.

Hey! Did I miss anything? Lol jk the world is on fire 😂 here's a thing I made https://t.co/g1SE45Rkrv — Joss Whedon (@joss) September 21, 2016

Clicking the link leads you to Save the Day, which is a production company designed to “fighting the apathy, cynicism, and honest confusion that keeps citizens from using their vote” and to push people to register to vote for the upcoming U.S. election. It’s not associated with any candidate—Save the Day also encourages people to vote in local, state, and federal elections—but its evident which candidate they’re trying to prevent entering the White House.

Whedon recruited his friends, many of whom are familiar faces from his movies, to record the incredibly self-aware PSA. They know that this many celebrities only come together to emphasize a message for something massively important like, as Don Cheadle put it, “a racist, abusive coward who can permanently damage the fabric of our society,” and they’re doing it anyway.

And if you do your part, Mark Ruffalo will do a nude scene in his next movie. We’re not sure he’s on board, but everyone else is completely serious. Just look at how much they repeat that pledge.
