Spider-Man has had an eventful year. He won an Oscar. He took home over $1 billion at the box office. And he was the center of a huge Hollywood battle that almost saw Marvel lose the rights to keep Spider-Man in the MCU. Thanks to Tom Holland, Spidey gets to remain within multiple epic universes.And when it comes to Sony Pictures' hit animated film, Spider-Man: Into the Spider-Verse, there's quite a few universes left to unpack. The first film ended on a cliffhanger that left fans wondering when they'd see Miles Morales next. Sony Pictures has officially confirmed that Miles is coming back to the big screen. We're just going to have to wait a few years. Here's what we know so far about the upcoming Into the Spider-Verse sequel.Sony Pictures confirmed via Twitter that we will see an Into the Spider-Verse sequel.On Friday, Nov. 1, Into the Spider-Verse's official Twitter account released a GIF with the number "2022" and the caption "April 8, 2022," confirming that the sequel will be out on that date. With the success of the first film, both critically and monetarily, it came as no surprise that a sequel is on its way.The film appears to be in development and is being written by Dave Callaham, who just wrote Zombieland: Double Tap. Dave is no stranger to writing for superhero universes. He's also credited as the screenwriter for the upcoming Wonder Woman sequel, Wonder Woman 1984, and in the midst of working on the upcoming Marvel movie, Shang-Chi and the Legend of the Ten Rings.Joaquim Dos Santos is being tied to the upcoming Into the Spider-Verse sequel as the director. This film will be Joaquim's first feature length movie, but he's previously directed Avatar: The Last Airbender and its spinoff Legend of Korra.As of yet, no plot has been released for the film, but there have been some hints.Into the Spider-Verse left off on a cliffhanger that saw that Gwen Stacy (Hailee Steinfeld) could once again travel between universes, when it appeared that the group of Spider-People had just closed that gate and sent everyone back to their own universes. The post-credits scene created even more confusion when another Spider-Man is shown to have created a "goober" that allows him to jump between universes.Spider-Man fans have recognized that the post-credits scene's Spider-Man is actually Spider-Man 2099 and he'll be playing a part in the sequel, with Oscar Isaac likely to reprise his role.But he's not the only Spider-Person joining the fray. We've Got This Covered claims that Iron Spider will be in the sequel, but not just any Iron Spider. The iconic Mary Jane Watson will be donning the suit, as she once did in The Amazing Spider-Man comics. Zoe Kravitz played MJ in the original film and will likely return to play the Iron Spider version of her as well.She won't be the only woman joining the fight, though. Spider-Woman Jessica Drew will be making her big screen debut in Into the Spider-Verse 2. Little is known yet about how Spider-Woman or Iron Spider will join the team, but it appeared in the post-credits scene that Spider-Man 2099 is rounding up all the Spider-People for some reason so he may be the one that is gathering the new superheroes for action. All we know for certain, though, is that 2022 can't come soon enough.
