Marvel Animation’s Marvel Zombies is creeping closer to its Disney+ debut, and the series just added even more familiar faces from the MCU. Alongside the updated synopsis, Marvel confirmed that three more veterans are officially on board.Paul Rudd returns as Ant-Man, Wyatt Russell will once again play U.S. Agent after his run in The Falcon and the Winter Soldier and Thunderbolts, and Tessa Thompson is back as Valkyrie. Thompson previously lent her voice to What If…?, so it’ll be exciting to see what the King of New Asgard brings to this darker corner of the multiverse.Disney also revealed a fresh synopsis for the show:”After the Avengers are overtaken by a zombie plague, a desperate group of survivors discover the key to bringing an end to the super-powered undead, racing across a dystopian landscape and risking life and limb to save their world.”Showrunner Bryan Andrews recently spoke about keeping surprises intact, despite leaks like the Funko Pop reveal of Blade Knight.”I would hope so, yes. I’m sure there’s some things that… I’m not as up to date with all the stuff that’s already out, but I bet you dollars to donuts that they haven’t mentioned, but I would hope that they haven’t mentioned a couple of things that we do want to be an honest surprise.“So, we’ll see. It’s up to marketing and such on how they want to let some of these secrets come out, but yeah. We hope that there are some surprises still left, so you can see the episode and go, ‘What?’ And then next thing you know, bing, and now you can purchase, you know, as opposed to purchase first before you even see the context in the episode.”The show also holds nothing back in terms of violence and gore, and Andrews elaborated on what fans can expect from that TV-MA label.”We did try not to be gratuitous about [language], but there’s like, a couple key parts where someone does say something because it just fits. Like that’s what I would say in that moment,” he explained. “So, I think the rating comes from the level of violence and or intensity of the moments that the characters find themselves in. And yeah, blood gets spilled, and we want to be able to see that.”The series already boasts a stacked cast, including Elizabeth Olsen (Scarlet Witch), Awkwafina (Katy), David Harbour (Red Guardian), Simu Liu (Shang-Chi), Randall Park (Jimmy Woo), Florence Pugh (Yelena Belova), Hailee Steinfeld (Hawkeye), Dominique Thorne (Ironheart), Iman Vellani (Ms. Marvel), Hudson Thames (Spider-Man), and Todd Williams in a secret role. Directed by Bryan Andrews with a script from Zeb Wells, Marvel Zombies counts Kevin Feige, Louis D’Esposito, Brad Winderbaum, Dana Vasquez-Eberhardt, Wells, and Andrews as executive producers, with Danielle Costa and Carrie Wassenaar producing.The undead storm arrives on September 24.
