Marvel Casts Sadie Sink in Spider-Man 4

Sadie Sink has been cast in Spider-Man 4.

Marvel announces that the first new actor joining Spider-Man 4 is Sadie Sink (Stranger Things). Her character has yet to be revealed, but Marvel says it will be an iconic redhead.

Some theories point to Mary Jane Watson since the MJ from Tom Holland's previous Spider-Man films that Zendaya plays is Michelle Jones. Other theories point to X-Men's Jean Grey since the X-Men reboot is releasing in a few years, and Marvel said that they will sprinkle in X-Men characters in other MCU films before they release the next X-Men film.

Spider-Man 4 is another multiverse movie that will release between "Avengers Doomsday" and "Avengers Secret Wars."
