In news announced at Disney's D23 Expo, Kat Dennings' Darcy Lewis and Randall Park's Jimmy Woo will both be returning to the Marvel Cinematic Universe in the upcoming Disney+ show WandaVision. Darcy worked as an intern for Erik Selvig and Jane Foster in the Thor movies, and Randall Park is an FBI agent who appeared as Scott Lang's parole officer in Ant-Man and the Wasp.
Disney+, the new streaming service for all things owned by Disney, launched on November 12, 2019. Within the first few years of its launch there will be a number of exclusive Marvel Cinematic Universe shows released on Disney+, including WandaVision, The Falcon and the Winter Soldier, and Loki. Three more shows were announced during Marvel's presentation at D23: Moon Knight, Ms. Marvel, and She-Hulk. There will also be an animated series, Marvel's What If..., which will explore what would happen if one thing was changed in each of the 23 MCU movies released so far.
Kat Dennings' Darcy Lewis made her first appearance in Thor (where she famously dubbed Thor's legendary hammer Mjolnir "mew-mew") and returned in the 2013 sequel Thor: The Dark World, but hasn't been seen since. Marvel Studios boss Kevin Feige took to the stage at D23 to announce that Dennings would be returning in WandaVision alongside Randall Park's Jimmy Woo, and that Kathryn Hahn has also joined the cast as a "nosy neighbor." Previously announced cast members are Paul Bettany and Elizabeth Olsen in their roles as Vision and Scarlet Witch, and Teyonah Parris as the grown-up Monica Rambeau (who appeared as a child in Captain Marvel).
WandaVision is set to release on Disney+ in spring 2021, coinciding with the release of Doctor Strange in the Multiverse of Madness, which Scarlet Witch will also be appearing in. It seems likely that WandaVision and the Doctor Strange sequel's stories will connect somehow. One theory is that Scarlet Witch, still mourning the loss of Vision, will use her reality-bending powers to bring him back to life and in the process become the cause of the Multiverse's madness.
How Jimmy Woo and Darcy fit into all of this remains to be seen. Wanda and Vision were technically fugitives in Avengers: Infinity War, but a lot of time has passed since then and the Sokovia Accords no longer seem to be an issue. Then again, Jimmy Woo's job does involve keeping rogue superheroes in check, so there are myriad ways he could be involved. Darcy's involvement, meanwhile, indicates that things may get cosmic in WandaVision - given that Darcy is one of the planet's foremost experts on wormholes.
