The upcoming Marvel film, Spider-Man: Brand New Day, has just dropped some exciting news. Liza Colón-Zayas, known for her role in The Bear, has joined the cast, although her character remains under wraps. Fans are speculating that she might play Rio Morales, setting the stage for Miles Morales to become a prominent player in the MCU.
### Rumors Surrounding Sadie Sink’s Role
There’s also buzz around Sadie Sink’s role in the movie, with rumors suggesting she might play Mayday Parker, the daughter of Tobey Maguire’s Peter Parker and Kirsten Dunst’s Mary Jane Watson from the Sam Raimi trilogy. This would mark Mayday’s first live-action appearance, and her connection to Tobey Maguire’s universe could hint at a multiverse storyline
### Plot Speculations
With the film’s release sandwiched between Avengers: Doomsday and Secret Wars, it’s likely that Spider-Man: Brand New Day will feature some multiversal elements. The story might explore Peter Parker’s role in the larger MCU, potentially setting up his appearance in Secret Wars. Some fans are hoping for a street-level narrative, but the involvement of multiple locations, including Italy and the UK, suggests a globe-trotting adventure similar to Spider-Man: Far From Home
