The mastermind behind Spider-Man: Brand New Day, director Destin Daniel Cretton, has given fans their first up-close look at some of the movie's enigmatic villains. In an Instagram post celebrating costume designer Sanja Milkovic Hays' work, Cretton unveiled images of both Boomerang and a leading female ninja from The Hand clan. These characters have been shrouded in mystery amidst the film's massive roster of baddies that remain largely unexplored. With just weeks left before launch, Sony and Marvel are keeping their secrets close to the vest. Fans have been especially curious about Boomerang, who has only made brief appearances in trailers so far. A popular theory suggests he might be MJ's new boyfriend, Eman Esfandi from Star Wars: Ahsoka. However, Cretton's post seems to show someone other than Esfandi wearing the costume, leaving fans questioning if this is a deliberate misdirect or just a stunt double in action. The female ninja leading The Hand, tagged in the photo, appears to be Fan Xiaoshuang, a stunt double and martial artist known for her work on Marvel films like The Marvels and Shang-Chi and the Legend of the Ten Rings. Fans wonder if she'll take on the lead role or is another stunt double. Cretton's post served as a shoutout to the talented artists behind the scenes, reminding us that thousands of passionate creators contributed their unique touch to every frame of the movie. Spider-Man: Brand New Day hits theaters on July 31, and the press tour has already started with Tom Holland hinting at his potential involvement in Avengers: Doomsday and Avengers: Secret Wars, suggesting he might feature in these upcoming Marvel films.
