2018's Spider-Man: Into the Spider-Verse is one of the best superhero films of all time. The multiversal affair saw Miles Morales' Spider-Man pull in other variants from separate universes, including Spider-Man Noir, Spider-Gwen, Spider-Ham, Peter B. Parker, and Peni Parker, following a science experiment gone wrong. After pulling in nearly $375 million at the global box office against a $90 million budget as well as winning Best Animated Picture, among others, Into the Spider-Verse is going to get a sequel later this year.

Having said that, the first part of Spider-Man: Across the Spider-Verse, which was confirmed last December has a tall and unenviable task of following up on such an iconic film. But, according to the film's writers, Across the Spider-Verse could end up getting help from several other established cinematic universes to make sure that it lives up to expectations.

During a Happy Sad Confused podcast, Christopher Miller and Phil Lord hinted at a potential crossover with the MCU and Sony's Spider-Man universe. Phil Lord specifically mentioned in the podcast that "Everything's possible except for this one thing that everyone wants."
