Sadie Sink Stays Silent as Speculation Swirls Around Her Spider-Man Role

by

The mystery surrounding who Sadie Sink is playing in Spider-Man: Brand New Day continues to grow.

The young actress recently told Entertainment Weekly that she’s good at keeping things confidential, while discussing the upcoming season of Stranger Things.

She mentioned that people generally trust her to be discreet, especially when discussing the Netflix show. This is a quality Destin Daniel Cretton, the director of Brand New Day, and the producers of the new superhero movie probably value.

Photos from the set consistently show the team working hard to hide details about her character, even covering her up with clothes and props.

Sadie Sink joked about her ‘Stranger Things’ co-star, Tom Holland, being instantly recognizable to fans even when he’s in costume. She explained that while Tom can easily wave to people who know him, she often goes unnoticed, feeling like a ‘penguin’ in comparison.

That’s not a hint, of course, since The Penguin is a DC character…

There are many Marvel characters Sadie Sink could portray, and fans enjoy guessing which one it might be.

Theories Abound

It’s doubtful that the actress with red hair will be playing Mary Jane Watson, Peter Parker’s famous girlfriend. Zendaya already plays MJ in this movie series. The role of Peter’s other love interest from the comics, Betty Brant, is also taken, with Angouri Rice cast in that part.

Despite the observation that hair color can change, Gwen Stacy, who is blonde, doesn’t seem to be undergoing a transformation. If Kiernan Shipka is portraying a regular, uncostumed character, there’s no need to conceal what she’s wearing.

Many fans believe Maya Sink will play Jean Grey, a powerful mutant with telekinetic and telepathic abilities. This idea gained traction even before Sink officially joined the Marvel Cinematic Universe, and Jean Grey was previously played by Famke Janssen and Sophie Turner in the X-Men films.

She explained that the situation began before she was assigned to the project. She was confused at first, saying she wondered what everyone was discussing.

Sadie Sink on fans thinking that she will portray Jean Grey in the MCU:

Honestly, all this buzz was happening before I even got involved with the movie. I remember hearing people talk about it and being totally confused – I was like, ‘Hold on, what’s going on?’

It’s not a definite rejection, and fan requests sometimes come true – just look at Patrick Stewart becoming Professor X!

The character of Sinking Island has been confirmed to appear in the upcoming Avengers: Secret Wars movie, expanding the potential for her storyline. Jon Bernthal will reprise his role as the Punisher in Brand New Day, though it’s currently unknown if he’ll be in any other Marvel films beyond that.

According to EW, a popular theory suggests the character Sink might actually be Rachel Cole-Alves, a supporting character from the Punisher comics. Sadie Sink, the actress who plays Sink, hasn’t denied this possibility.

Sink stated that everyone will need to wait for the situation to resolve. She expressed optimism that things would eventually be settled.

Conclusion

For fans, the fun is in the waiting.

I’m really enjoying the buzz about Sadie Sink potentially joining the Spider-Man: Brand New Day cast! It’s nice to see the focus be on her talent and the movie itself, instead of getting bogged down in actors sharing their political views – which, honestly, can be a distraction from enjoying the film.

Instead of causing conflict with opinions on sensitive topics or criticizing fans, Sadie Sink is letting her audience speculate and enjoy the mystery. This approach creates a positive and refreshing experience for fans who have been longing for something lighter and more hopeful.
