The Marvel Cinematic Universe is headed into some surprising places in the next few years, with new movies and Disney+ exclusive television shows continuing to bring beloved characters to life. Easily one of the most anticipated on that upcoming roster has been Fantastic Four, Marvel Studios’ long-gestating take on Marvel’s First Family after several underwhelming incarnations from other studios. While a lot is still unknown about Fantastic Four — especially its principal four cast members, who continue to be debated about endlessly on social media — the film is gradually on its way to becoming a reality, with WandaVision’s Matt Shakman lined up to direct, and Jeff Kaplan and Ian Springer on deck to write. As we inch closer to Fantastic Four and whatever MCU connections it ends up having, one theory has already popped up among some Marvel fans — that Jennifer Walters / She-Hulk (Tatiana Maslany) should factor into the film in some way.
