Spider-Man: Across the Spider-Verse is a 2023 American computer-animated superhero film featuring the Marvel Comics character Miles Morales / Spider-Man, produced by Columbia Pictures and Sony Pictures Animation in association with Marvel Entertainment, and distributed by Sony Pictures Releasing. The sequel to Spider-Man: Into the Spider-Verse (2018), it is set in a shared multiverse of alternate universes called the Spider-Verse. The film is directed by Joaquim Dos Santos, Kemp Powers, and Justin K. Thompson (in Dos Santos and Thompson’s feature directorial debuts), from a screenplay written by Phil Lord, Christopher Miller (who both also produce) and David Callaham. Shameik Moore voices Miles, starring alongside Hailee Steinfeld, Brian Tyree Henry, Luna Lauren Vélez, Jake Johnson, Jason Schwartzman, Issa Rae, Karan Soni, Daniel Kaluuya, and Oscar Isaac. In the film, Miles goes on an adventure with Gwen Stacy / Spider-Woman across the multiverse where he meets a team of Spider-People known as the Spider-Society, led by Miguel O’Hara / Spider-Man 2099, but comes into conflict with them over handling a new threat in the form of the Spot.
On Earth-65, Gwen Stacy lives with her father, police captain George, who is unaware that she is Spider-Woman. Years prior, Gwen accidentally caused the death of her best friend Peter Parker while he was mindlessly rampaging as the Lizard, and the police have been hunting her ever since. One night, Gwen encounters a version of the Vulture from an Italian Renaissance–themed alternate universe. Spider-People Miguel O’Hara and Jessica Drew arrive using portal-generating watches and help Gwen subdue the Vulture. Gwen reveals her identity to George; distraught by the revelation, he attempts to arrest her. Miguel begrudgingly grants Gwen membership into his Spider-Society and she escapes through a portal with him and Jess.
In Brooklyn on Earth-1610, sixteen months after the Alchemax collider’s destruction,[a] Miles Morales misses Gwen and clashes with his parents. As Spider-Man, Miles encounters the Spot, an Alchemax scientist whose body was infused with portals after the collider explosion. The Spot blames Miles for his condition and reveals that, while originally testing the collider, he transported a spider from Earth-42 that later bit Miles. Later on, the Spot travels into a void, where he learns to travel to other universes containing colliders to empower himself further.
