Immediately, the Marvel fandom went into overdrive, trying to predict who Sadie Sink could be playing in the MCU. The guesses weren’t all that imaginative: Sink’s red hair sparked “Mary Jane” or “Jean Grey” guesses – other fans were willing to consider a dye job that would allow Sink to finally bring Felicia Hardy/Blackcat to the Spider-Man films. However, there’s another theory going around that ties Sink to a much more pivotal character – one who could bring the MCU and the animated Spider-Verse films together.
Gwen Stacy’s Ghost-Spider/Spider-Gwen has become one of the most popular characters in Marvel over the last decade, breaking out of comics into the animated movies (Spider-Man: Into the Spider-Verse, Spider-Man: Across the Spider-Verse) and animated TV series (Spidey and His Amazing Friends), as well as merchandising. The only place that Spider-Gwen hasn’t broken out (yet) is in the live-action films, but the timing oddly aligns for her to make an appearance in Spider-Man 4.
Across the Spider-Verse ended on the cliffhanger of (SPOILERS) Miles Morales accidentally being transported to the home dimension (Earth-42) of the interdimensional spider that gave him his powers. There Miles found a world that never got its Spider-Man, and his own variant self became the evil gang leader The Prowler, a villain who quickly captures Miles as his prisoner. Meanwhile, Gwen went looking for Miles on his homeworld of Earth-1610, only to realize he’d been displaced. Gwen used her Spider Society tech and connections to start hopping dimensions and collecting other Spider-Men as a cavalry to rescue Miles – who’s to say that she doesn’t make a stop on Earth 616?
The Spider Society scenes of Across the Spider-Verse established that these animated films exist in the same multiverse as all three iterations of the live-action Spider-Man movies; Spider-Man: No Way Home has already established this MCU Spider-Man can make buddies with his variants. At the end of the day, fans want to see Peter, Miles, and Gwen web-slinging together at some point in the MCU – maybe that day is coming sooner than we think?

It would be a major swing (pun) – the exact kind the MCU needs right now. Spider-Man 4 would conceivably see Gwen and Peter making contact as the entire Marvel Multiverse is unraveling – a storyline that could continue into Spider-Man: Beyond the Spider-Verse as Gwen and Peter help save Miles and help preserve his world – at least long enough for it to be ripped apart anyway, and the gang of Spider-People all end up on Battleworld for Avengers: Secret Wars. After Secret Wars, the rebooted MCU would have multiple Spider-Man characters to play with, and both the characters and their live-action actors would all be firmly established.
Is Sadie Sink Playing Spider-Gwen In Spider-Man 4?
As stated, most Marvel fans immediately made the most obvious visual associations with Sadie Sink and characters like Jean Grey/Marvel Girl/Phoenix, mostly due to the redhead connection. However, when you consider the animated version of Gwen in the Spider-Verse movies, she’s not too far off from Sadie Sink with a fade haircut.
The live-action Spider-Gwen can’t be played by her animated voice actress, since that voice actress (Hailee Steinfeld) is already playing another live-action MCU character: Kate Bishop/Hawkeye. Animated Gwen (and Miles, guys…) will have to recast for live-action (whether they’re the Spider-Verse characters or new variants), and Sadie Sink isn’t a crazy choice for that. At all (see above).
