Exciting news has surfaced for Marvel fans as Stranger Things star Sadie Sink is reportedly joining the MCU in the highly anticipated Spider-Man 4, alongside returning lead actor Tom Holland as Peter Parker. The film is slated to begin filming later this year under the direction of Destin Daniel Cretton, with Marvel president Kevin Feige and Amy Pascal producing.
While no official confirmation has been given regarding Sink’s character, speculation is running wild among Spider-Man fans, with many guessing she could be playing one of three iconic characters from Marvel lore.
Some fans are still hopeful that Sink will take on the role of Jean Grey, after rumors last year hinted that she was a top contender to portray the beloved X-Men mutant. This speculation has led to buzz that the X-Men could finally be integrated into the MCU, potentially kickstarting a new era for the franchise.
One fan shared their excitement on X, writing, “Jean Grey here we come,” while another added, “I can totally see her as a young Jean Grey, which builds up for the arrival of a younger X-Men for the MCU.”
However, Jean Grey isn’t the only character fans are considering. Some are suggesting that Sink could be playing Gwen Stacey, the iconic love interest of Peter Parker, while others believe she might be cast as Black Cat, another popular character from Spider-Man’s universe. “Sadie Sink as Black Cat would be perfect casting,” tweeted one fan, while another said, “I’m guessing Black Cat.”
Sink’s distinctive red hair has also led some fans to speculate that she could be taking on the role of Mary Jane Watson, Spider-Man’s longtime love interest. However, not all fans are on board with this theory, with some expressing concern about Zendaya’s chemistry with Tom Holland in the role of MJ. “I hope they don’t replace Zendaya… the chemistry between Tom and Zendaya is irreplaceable,” one fan commented.
While fans eagerly await the confirmation of Sink’s role, it is believed that her character will play a significant part in the upcoming film. Spider-Man 4 is expected to explore the aftermath of Peter Parker erasing his identity in Spider-Man: No Way Home, which saw him deal with the consequences of Doctor Strange’s spell.
Spider-Man 4 is set for release on July 24, 2026, just two months after Avengers: Doomsday. Fans will have to wait a little longer to discover which iconic Marvel character Sink will bring to life in the MCU.
