So, why is that happening on the small-screen, and not in some massive blockbuster movie epic five years from now? It's a massive, massive story, and fans have been speculating about its inclusion ever since Captain Marvel introduced the Skrulls to the MCU.
Secret Invasion, as you may have heard, is a 2008 comic book storyline that features the shapeshifting aliens known as the Skrulls infiltrating Earth by abducting various Marvel heroes and taking their place, destablizing the entire superhero community and, by extension, the Earth itself. One of the biggest Marvel Studios Disney+ announcements so far - even with things like WandaVision, The Falcon and the Winter Soldier, Loki, and more in mind - came during Disney's Investor Day presentation in December when Feige revealed that a series inspired by the comic book epic Secret Invasion would arrive on the streaming service in the future. With that in mind, how do Feige and his team figure out what goes where? Though we've seen small-screen tie-ins to the MCU before in the form of series like Agents of S.H.I.E.L.D., Marvel Studios head Kevin Feige has been clear that the Disney+ era will feature streaming series with much more direct ties to the big-screen future of the universe, as the shows feed into the films and the films feed into the shows.
This week, an entirely new storytelling avenue opens for the Marvel Cinematic Universe with the launch of its first live-action Disney+ series, WandaVision.
