Sadie Sink Revealed as Jean Grey in Spider-Man: Brand New Day

Actress Sadie Sink was confirmed to portray the X‑Men mutant Jean Grey in Marvel’s new Spider‑Man film, "Brand New Day". Marvel Studios kept the casting a secret throughout production, even assigning the character a fake script codename (“Denim Red”) to conceal her identity. Kevin Feige explained the secrecy was intended to protect the opening‑weekend experience and noted that Grey’s age and powers fit the story’s themes.

The film opened to a record‑breaking global box‑office, earning roughly $927 million in its first weekend and surpassing $1 billion within six days, making it the second‑fastest film ever to reach that milestone. Domestic (U.S. and Canada) earnings were about $407 million, with the remainder from international markets. The success follows a long‑running promotional mystery that sparked widespread fan speculation about Sink’s role.

Sink later discussed the experience, saying she found it easy to keep the secret and that only close friends and family knew the truth. The reveal positions Jean Grey as the first major X‑Men character to appear in the Marvel Cinematic Universe, setting up future storylines for the franchise.
