Sadie Sink has become one of the most anticipated newcomers in the Marvel Cinematic Universe (MCU), with multiple projects in the works. In a recent interview, she revealed her participation in the casting process for the new X-Men film, explaining how she met with Jake Schwanke early in the development phase. ‘I met with him the first time he came to see John Proctor,’ she said. ‘It was this weird thing of being at the early stages of putting X-Men together, but he knew I was the only piece of the puzzle at that point, because I was the only mutant that had been established.’

How She Landed the Role of Jean Grey

Sadie confirmed that she did not audition for the role of Jean Grey. Instead, Marvel executives Kevin Feige and Louis D’Esposito reached out to her directly, sharing their long-term vision for the character. ‘The more that I learned about the character, the more I just got really excited about it and excited about this version of her too, which just feels really complex and different from what we’ve seen,’ she said in an interview with Vanity Fair. The new X-Men movie is currently scheduled for a 2028 release.

Spider-Man: Brand New Day Keeps Her Identity a Secret

While details about her X-Men role are emerging, her role in ‘Spider-Man: Brand New Day’ remains tightly guarded. The actress confirmed that Marvel Studios will not reveal her character until the film’s theatrical release. In a promotional video shared in connection with the film’s Chinese release, Sink joked about the many fan theories circulating online, clarifying that she does not play Spider-Man or Aunt May. ‘Now that it’s out and X-Men is being talked about and it’s happening, it’s so exciting to think about what’s next for her,’ she added.

Marvel has kept the details of Sink’s character intentionally vague, with the actress appearing only briefly in trailers and never in full view. This secrecy has only heightened fan anticipation. The studio appears to be using this strategy to preserve one of the film’s biggest surprises, as ‘Brand New Day’ has already become one of the most anticipated films of the year without revealing much about Sink’s role.

Speculation About X-Men Involvement

One of the most popular theories is that Sadie Sink will portray Jean Grey, a key X-Men character. This speculation has been fueled by hints in the trailers and her involvement in the X-Men project. While no official confirmation has been made, the fact that she is being linked to a major Marvel superhero role has led fans to believe she may be playing one of the franchise’s most iconic characters. If this is the case, Sink could become one of the defining faces of the MCU in the 2030s.

Despite the mystery surrounding her character, Sadie Sink has expressed excitement about the future of the MCU. ‘It’s interesting to be at the very beginning of it,’ she said, referring to the development of the X-Men series. As production timelines remain undisclosed, fans will have to wait until 2028 to see what Marvel has in store for Jean Grey and the X-Men as a whole.
