The speculation about this kind of stuff is only going to increase until Spider-Man: No Way Home is scheduled to open in theaters on December 17.
Holland himself, who is notoriously bad about keeping spoilers secret, told Empire that he doesn’t know if they’re in the movie.
But the only names confirmed from those previous films so far are Alfred Molina’s Doctor Octopus and Jamie Foxx’s Electro.
It’s known that Marvel’s Spidey (Tom Holland) and Doctor Strange (Benedict Cumberbatch) open up some kind of hole in the multiverse (of madness), which results in Holland’s Peter Parker encountering villains from previous Spider-Man movie franchises.
