When last we saw Spider-Man, Peter Parker was in a very precarious position: J. Jonah Jameson (J.K. Simmons) had just revealed that Parker is Spider-Man. With fake footage suggesting that Spidey ruthlessly killed Mysterio (Jake Gyllenhaal) now out in the world, Peter seems set to find himself on the run in his next film.

The larger story, though, isn't anything from Spider-Man: Far From Home, but all the rumors surrounding the possibility of a multiverse team-up for the third film. We know Benedict Cumberbatch's Doctor Strange is appearing in Spider-Man 3. We also know that the Doctor Strange sequel is called Doctor Strange in the Multiverse of Madness, suggesting that the multiverse could play a major role for Spider-Man as well.

Additionally, in Spider-Man 3, Jamie Foxx is playing some version of Electro, a character he played back in Amazing Spider-Man 2, and Alfred Molina is supposedly returning as Doc Ock, a role he originally took on in Spider-Man 2. Two other names whose rumored returns seem more and more likely are Amazing Spider-Man actor Andrew Garfield and original Mary Jane Watson actress Kirsten Dunst. Heck, there's even a rumor out there saying Charlie Cox will play Daredevil in Spider-Man 3, even though his Netflix series is long over.

All of this is to say that Holland could have just completed filming with any or all of these people before he posted that photo to Instagram. And, of course, the biggest question of all is if original live-action movie Spider-Man Tobey Maguire is returning — a possibility which has yet to be formally confirmed at all. Still, we can't imagine a bigger scene than Holland and Maguire's Spidey's meeting up for the first time.

On the flip side, maybe Holland's brother Harry has a role in Spider-Man 3, and that's why the day of filming was so special for him. In any case, all shall be revealed when Spider-Man 3 hits theaters on December 17, 2021.
