Spooky season is getting an early start this year. Disney+ just unveiled the trailer for Marvel Zombies, and it looks like a ghoulishly good time. The four-episode series, which is a spin-off of the What If…? episode What If… Zombies?!, is set to premiere on September 24.

Marvel Zombies takes place during a zombie apocalypse and centers on a group of survivors who are forced to step up and save the day after the Avengers become infected. Expect things to get pretty gruesome: This is the first Marvel Animation series to earn a TV-MA rating.

Marvel Zombies features the return of several fan-favorite MCU characters, with a stacked voice cast that includes Elizabeth Olsen, Paul Rudd, Florence Pugh, David Harbour, Tessa Thompson, Simu Liu, Awkwafina, Hailee Steinfeld, Wyatt Russell, Randall Park, Iman Vellani, Dominique Thorne, and more.

The series is created by Bryan Andrews and Zeb Wells. Kevin Feige, Louis D’Esposito, Brad Winderbaum, Dana Vasquez-Eberhardt, Bryan Andrews and Zeb Wells serve as executive producers. Danielle Costa and Carrie Wassenaar are producers.
