Leaked Spider-Man: Brand New Day Trailer Teases Tom Holland and Sadie Sink Showdown

Well, this is not the Marvel leak people were waiting for. Everyone had their eyes peeled for shaky Avengers: Doomsday cam footage the moment it hit theaters. Instead, the thing making the rounds is an alleged trailer for Spider-Man: Brand New Day. Not exactly on the bingo card, but here we are.

What the leaked clip supposedly shows

The trailer reportedly opens on Tom Holland’s voice over — very much a post-No Way Home vibe about the cost of that spell and why Peter had to do it:

"Hi, my name is Peter Parker. You don’t remember me, but we used to know each other. Something bad was gonna happen, and the only way to stop it...was to make everyone forget about me. Because I’m not just Peter Parker, I’m Spider-Man. And sometimes, Spider-Man has to do the hard thing, even if it breaks Peter Parker’s heart."

Audio cues in the clip hint at a tense back-and-forth with Jon Bernthal’s Punisher, warnings tied to Sadie Sink’s mystery character, and a quick-cut montage that looks unfinished but lines up with villains tied to recent casting buzz. The original uploads were pulled down, but the conversation hasn’t slowed at all.

One line fans keep quoting is from Sink’s character in the alleged footage:

"Stay out of my way or it won’t just be your friends who don’t remember peter parker."

So who is Sadie Sink playing?

Sink is jumping from Stranger Things straight into the MCU, and Marvel-level secrecy is doing what it always does: sending fandom into theory overdrive. People are guessing everything from classic comic legacies to mutant connections, and yes, the red hair is apparently a plot point now.

Speaking to Entertainment Weekly, Sink addressed the hair talk with a shrug:

"A lot of people forget that hair color can change, but yeah, I understand all of the theories."

She would not say who she’s playing (shocker):

"People will just have to wait and see. I’m excited for all of it to maybe be put to rest."

As for the Jean Grey rumor that keeps boomeranging back, she says that one predated her even knowing she’d booked this movie:

"That was happening before I even knew that I would be working on this project. I was like, ‘Wait! What are people talking about?’"

Deadline first reported in March that Sink had joined Spider-Man: Brand New Day in an undisclosed role, alongside Tom Holland and Zendaya.

Who’s in this thing and when do we see it?

Spider-Man: Brand New Day is currently set for July 31, 2026 — landing a little over a year after The Fantastic Four: First Steps. The cast so far points to a very street-level, fists-and-bullets type of conflict, with one big green exception that feels intentionally placed more than random.

• Tom Holland — Peter Parker/Spider-Man
• Sadie Sink — role unconfirmed
• Jon Bernthal — Frank Castle/Punisher
• Mark Ruffalo — Bruce Banner/Hulk
• Zendaya — MJ
• Jacob Batalon — Ned Leeds
• Michael Mando — Mac Gargan/Scorpion
• Liza Colon-Zayas — role unconfirmed
• Tramell Tillman — role unconfirmed
• Marvin Jones III — Tombstone

Ruffalo’s Banner has barely shared meaningful screen time with Peter, so dropping him here reads like a choice with a capital C. And Bernthal’s presence basically guarantees things get ugly at street level.

What to make of the leak

As always with this stuff: grain of salt. Clips vanish, mirrors pop up, the cycle repeats. But if the audio and those quick shots are legit, Marvel’s setting Peter up for a new status quo that leans into the consequences of that forget-everything fix — and maybe someone who wants to push it even further.

The Sadie Sink question is the fun one: is she protecting Peter, trying to control him, or looking to erase him from more than just memories? Drop your wildest theory — being confidently wrong together is half the fun.

Spider-Man: Brand New Day is currently slated to hit theaters July 31, 2026.
