As far as we know, Elizabeth Olsen isn’t involved in Spider-Man: No Way Home, but she has been rumored for a cameo appearance just like virtually anyone to have ever appeared in either a Sony or Marvel Studios movie involving the web-slinger in some fashion over the last two decades.
Whether she winds up putting in an appearance or not, we can gather that Tom Holland’s third solo outing will be the middle chapter in a multiversal trilogy, bookended by Disney Plus’ WandaVision and next March’s Doctor Strange in the Multiverse of Madness. So, even if Scarlet Witch doesn’t show up in person during No Way Home, you can guarantee that her fingerprints will still be all over the broad strokes of the plot.
Of course, the majority of the most recent speculation surrounding the MCU threequel has revolved around the Sinister Six, with three members each hailing from both the Sam Raimi and Marc Webb timelines. And we’ve now heard from our sources – the same ones who told us Captain America 4 with Anthony Mackie was in the works long before it was confirmed – that Wanda will be responsible for them entering the MCU.
According to our information, it’ll be tied to WandaVision‘s post-credits scene, where the franchise’s most powerful hero hears her children calling out to her from a different reality. This causes Scarlet Witch to go on a tear through the multiverse to try and find them, with the butterfly effect eventually weakening the barriers and allowing Green Goblin, Sandman, Doctor Octopus, Lizard, Electro and Rhino to make their way to the present day timeline where they’ll cause some serious trouble for Peter Parker, presumably leading to Spider-Man: No Way Home‘s protagonist roping in a bit of multiversal backup of his own to try and even the odds in his favor.
