Elizabeth Olsen is finally back as Scarlet Witch in “Marvel Zombies,” albeit just in a voice role. The four-episode Disney+ animated series is a spinoff of “What If…?” and is set in a world where most of the population, including the Avengers, are zombies. Olsen voices her fan favorite superhero alongside many returning Marvel alum, including Paul Rudd as Ant-Man, Iman Vellani as Ms. Marvel, Simu Liu as Shang-Chi and more.

“I truly recorded that years ago. I can’t remember anything,” Olsen admitted at L.A. Comic Con (via GamesRadar) when asked about her Scarlet Witch return. “I need to watch it. I have no idea what [happens in] ‘Marvel Zombies.’”

Olsen continued, “It’s my voice. I did it in my house, I wasn’t even in an office space. This must have been 2020, 2021? Why was I working in my house and not in a studio? I really have no idea what it was like. I’m so sorry.”

Olsen debuted as Scarlet Witch in the post-credits scene of 2014’s “Captain America: The Winter Soldier” before her proper supporting role in 2015’s “Avengers: Age of Ultron.” She has since gone on to star in blockbusters like “Avengers: Infinity War” and “Doctor Strange in the Multiverse of Madness” and headlined the Disney+ series “WandaVision,” for which she earned an Emmy nomination.

The “Doctor Strange” sequel remains Olsen’s last in-person Marvel appearance as Scarlet Witch. The movie turned the character into a full blown villain and ended with Scarlet Witch crushed under a collapsed building. Her fate is unknown, and neither Olsen nor Marvel have yet to announce when Scarlet Witch will reappear. She has not been announced as a cast member for next year’s “Avengers: Doomsday.”

Olsen said last year she’s open to reprising Scarlet Witch in the Marvel Cinematic Universe, but only if there’s a way to use the character well.

“It’s a character that I love going back to when there’s a way to use her well, and I think I have been lucky that when I started I was used well,” Olsen said in a recent interview with FM104 (via Collider). “People didn’t know what to do with me for a second there. … If there’s a good way to use her I’m always happy to come back.”

All four episodes of “Marvel Zombies” are now available to stream on Disney+.
