In an interview with Phil Lord and then-Sony chief Amy Pascal for Vanity Fair in 2018, it was revealed that Spider-Man: Into the Spider-Verse 2 would focus heavily on a romance between lead teen hero Miles Morales and his interdimensional fellow webslinger Gwen Stacy, referred to as Spider-Gwen by her solo comic book series’ title alone.
The concept of this romance, which is canon to their Marvel comics storylines, was included in Lord’s original draft of the first film’s screenplay, until it was cut to ensure the additional Spider-characters could share equal time in the spotlight.
