Overview

• The premiere has been moved up from its original October 3 date to September 24, positioning the series earlier in Disney+’s fall lineup.
• The TV-MA rating reflects the show’s focus on intense violence, significant character deaths and emotional stakes rather than gratuitous gore.
• Originally conceived as a standalone film, the project was restructured into a four-episode mini-event to maintain a cinematic through-line under showrunner and director Bryan Andrews.
• Marvel Zombies continues the cliffhanger from the What If...? episode “What If... Zombies?!,” following a new team of survivors against a quantum virus and zombified heroes.
• An ensemble of MCU actors—including Elizabeth Olsen, Iman Vellani, Simu Liu, Florence Pugh, Hailee Steinfeld, Dominique Thorne, David Harbour, Awkwafina, Randall Park and Hudson Thames—returns to voice their roles.
