Hey, what happened to Wanda’s accent?
While Marvel directors Joe and Anthony Russo have addressed the disappearing accent, originally set to be from the fictional Sokovia in 2015’sAvengers: Age of Ultron, Olsen gave a more open-ended answer toColliderabout the future of the accent.

But the difficulty of the accent doesn’t mean it’s going away forever.
“The Sokovian accent took a lot of time. It hasn’t gone anywhere. There have been reasons for everything. It lightened up when she started living in the States, and inWandaVisionshe is playing the role of being in an American sitcom and so it’s not gone. It is absolutely still there,” Olsen explained.
The Russo brothers had a similar explanation, pointing out that the accent slightly disappearing matched with Wanda becoming a spy.
“One is you’ll notice at the beginning ofCivil Warthat Black Widow is training her to be a spy, and two is she’s been on the run, and one of the most distinguishing characteristics that she has is her accent,“they explained in 2018.
WandaVision, exploring the relationship between Wanda and Paul Bettany’s Vision, is streaming on Disney+ now as the first of several Marvel series planned.
