Heidi Klum's Halloween costume may have exposed secrets about 'The Batman Part II'

Clues about the villains in Robert Pattinson's upcoming Batman sequel may have been accidentally revealed in an Instagram post about Heidi Klum's Halloween costume.

The supermodel dressed as a giant, gruesome severed hand for Halloween, complete with replicas of her wedding rings — and a behind-the-scenes post showing the costume's creation appears to reveal objects linked to several Batman villains.

Eagle-eyed social media users spotted the items in what is reportedly the workspace of special effects makeup artist Mike Marino, who created Klum's costume and previously worked on 2022's The Batman and its HBO spinoff, The Penguin .

Among the objects visible was a facial cast that fans said resembled actor Brian Tyree Henry with a disfigured lip. Some connected it to Two-Face, a Batman villain who was once Gotham City's district attorney, Harvey Dent, before an attack left half his face disfigured.

The image also showed a box labeled "Zsasz." Victor Zsasz is the name of a serial killer from the comics who carves tally marks into his skin for each person he kills.

The post has renewed speculation about Sebastian Stan's role in the upcoming film. In June, entertainment journalist Jeff Sneider reported that Stan would play Zsasz in The Batman Part II , while Henry would portray Harvey Dent / Two-Face. Neither casting claim has been officially confirmed.

Another box was labeled "Owl 3," which fans have speculated could refer to the Court of Owls, a secret society that influences Gotham City in DC Comics.

Marino confirmed his involvement in The Batman Part II in an October interview with W magazine , adding to speculation that the objects could be connected to the sequel. "To be honest, I'm a comic book nerd, so the fact that I'm working on [ The Batman: Part II ] is a dream scenario," he said. "We're doing some really cool makeup in this new movie, so that's the dream right there."

However, none of the apparent clues have been confirmed to belong to the new movie, and there is no indication that the objects were deliberately included in the Halloween post as hints about it. Yahoo has contracted Marino for comment.

Director Matt Reeves confirmed Henry and Stan's involvement in the sequel in May but did not reveal which characters they would play. Variety said Stan was "set to play" Harvey Dent.

Stan told the Happy Sad Confused podcast in an episode released in October that the movie is "going to be great," adding, "This is definitely, for me, feeling like something very different than I've gotten to do. And that's what I love, and I'm excited about."

The Batman Part II is scheduled to hit theaters on Feb. 18, 2028. It was originally due for release in October 2025 but was delayed by the Hollywood strikes.

Production was temporarily halted last month as Reeves stepped away for personal reasons . Ocean's Eleven director Steven Soderbergh was hired to help finish filming. The original movie was released in March 2022.
