Joss Whedon has assembled one of his largest casts ever to speak out against Donald Trump, “a racist, abusive coward who could permanently damage the fabric of our society.”

The Avengers director has released a new star-studded “Save the Day” PSA to encourage people to get out on Election Day and vote for Hillary Clinton. Featuring A-list talent like Robert Downey Jr., Mark Ruffalo and Julianne Moore, the video encourages people to put an end to “this nightmare before it even begins” and elect the candidate who isn’t famous for firing people.

Among the many TV stars featured in the LOL video: Nathan Fillion (Castle), Clark Gregg (Marvel’s Agents of S.H.I.E.L.D.), Jesse Williams (Grey’s Anatomy), James Franco (11.22.63), Neil Patrick Harris and Cobie Smulders (How I Met Your Mother), Taran Killam (Saturday Night Live), Yvette Nicole Brown (The Odd Couple), Tom Lenk (Buffy the Vampire Slayer) Bradley Whitford (Transparent), Keegan-Michael Key (Key & Peele), Matt McGorry (How to Get Away With Murder), Randall Park (Fresh Off the Boat), Ashley Johnson (Blindspot), Stanley Tucci (Fortitude), Leslie Odom Jr. (Smash), Don Cheadle (House of Lies) and Martin Sheen (Grace and Frankie).
